Libcurl Install and Use Issues
|
||||
Awaiting an Answer for Win 32 Install
|
||||
res = curl_easy_perform(curl); Error
|
||||
Makefile Issues
|
||||
|
||||
|
||||
Having previously done a thorough review of what was available that met my
|
||||
requirements under GPL, I settled for Libcurl as the software of choice for
|
||||
many reasons not the least of which was the support.
|
||||
|
||||
Background
|
||||
----------
|
||||
|
||||
This quest started when I innocently tried to incorporate the libcurl library
|
||||
into my simple source code. I figured that a few easy steps would accomplish
|
||||
this without major headaches. I had no idea that I would be facing an almost
|
||||
insurmountable challenge.
|
||||
|
||||
The main problem lies in two areas. First the bulk of support for libcurl
|
||||
exists for a Unix/linux command line environments. This is of little help when
|
||||
it comes to Windows O/S.
|
||||
|
||||
Secondly the help that does exist for the Windows O/S focused around mingw
|
||||
thru a command line argument environment.
|
||||
|
||||
You may ask "Why is this a problem?"
|
||||
|
||||
I'm using a Windows O/S with DevCpp. For those of you who are unfamiliar with
|
||||
DevCpp, it is a window shell GUI that replaces the command line environment
|
||||
for gcc. A definite improvement that I am unwilling to give up. However using
|
||||
DevCpp presented its own set of issues. Inadvertently I also made some
|
||||
careless errors such as compiling the 7.14 version of Makefile with an older
|
||||
version of source code. Thanks to Dan Fandrich for picking this up.
|
||||
|
||||
I did eventually with the help of Daniel, Phillipe and others manage to
|
||||
implement successfully (the only mingw available version)
|
||||
curl-7.13.0-win32-ssl-devel-mingw32 into the DevCpp environment. Only the
|
||||
dynamic libcurl.dll libcurldll.a libraries worked. The static library which I
|
||||
was interested in did not. Furthermore when I tried to implement one of the
|
||||
examples included with the curl package (get info.c) it caused the executable
|
||||
to crash. Tracing the bug I found it in the code and function res =
|
||||
curl_easy_perform(curl);.
|
||||
|
||||
At this point I had to make a choice as to whether invest my limited
|
||||
time-energy resource to fixing the bug or to compile the new version
|
||||
available. After searching the archives I found a very similar or the same bug
|
||||
reported from version 7.12x on. Daniel did inform me that he thought that this
|
||||
bug had been fixed with the latest version. So I proceeded to compile the
|
||||
latest SSL version where I faced other challenges.
|
||||
|
||||
In order to make this process unremarkable for others using the same
|
||||
environment I decided to document the process so that others will find it
|
||||
routine. It would be a shame if newbies could not implement this excellent
|
||||
package for their use.
|
||||
|
||||
I would like to thank the many others in this forum and in the DevCpp forum
|
||||
for their help. Without your help I may either have given up or it would have
|
||||
taken me many times longer to achieve success.
|
||||
|
||||
The Cookbook Approach
|
||||
---------------------
|
||||
|
||||
This discussion will be confined to a SSL static library compilation and
|
||||
installation. Limited mention and comments will be inserted where appropriate
|
||||
to help with non-SSL, dynamic libraries and executables.
|
||||
|
||||
|
||||
Using Makefile from DevCpp to compile Libcurl libraries
|
||||
|
||||
Preamble
|
||||
--------
|
||||
|
||||
Using the latest version release - curl-7.14.0.tar.gz. Curl source code is
|
||||
platform independent. This simply means that the source code can be compiled
|
||||
for any Operating System (Linux/Unix Windows etc. and variations of thereof).
|
||||
|
||||
The first thing to note is that inside curl-7.14.0 you will find two folders
|
||||
lib and src. Both contain Makefile.m32 (required for win mingw library or exe
|
||||
compilation) files which are different. The main difference between these two
|
||||
folders and the makefiles is that the src folder contents are used to compile
|
||||
an executable file(curl.exe) while the lib folder contents are used to compile
|
||||
a static (libcurl.a) and dynamic (libcurl.dll & libcurldll.a) file that can be
|
||||
used to compile libcurl with your own source code so that one can use and
|
||||
access all libcurl functions.
|
||||
|
||||
Before we start please make sure that DevCpp is installed properly. In
|
||||
particular make sure you have no spaces in the name of any of the directories
|
||||
and subdirectories where DevCpp is installed. Failure to comply with the
|
||||
install instructions may produce erratic behaviour in DevCpp. For further info
|
||||
check the following sites
|
||||
|
||||
http://aditsu.freeunixhost.com/dev-cpp-faq.html
|
||||
http://sourceforge.net/forum/message.php?msg_id=3252213
|
||||
|
||||
As I have mentioned before I will confine this to the SSL Library compilations
|
||||
but the process is very similar for compilation of the executable - curl.exe;
|
||||
just substitute the src folder makefile in its stead.
|
||||
|
||||
First use a text processor Notepad, or your own favourite text processor. To
|
||||
engage your favourite text processor, select Makefile.m32 click once with your
|
||||
mouse on file icon; icon turns blue, press the shift key and right-click on
|
||||
mouse, menu appears select "Open with", select your favourite text processor.
|
||||
|
||||
Next read the contents of Makefile.m32. It includes instructions on its use.
|
||||
|
||||
Method I - DOS Command Line
|
||||
---------------------------
|
||||
|
||||
Note - The only reason I have included this method is that Method II which is
|
||||
the preferred method for compiling does not allow for the setting of option
|
||||
switches (e.g. SSL = 1 or SSL =0). At least that's what they tell me at the
|
||||
Dev-Cpp forum.
|
||||
|
||||
1 - Make a copy of (D:\Dev-Cpp\bin) bin folder and name it "bin Original"
|
||||
place it in the Dev-Cpp installed directory (D:\Dev-Cpp\ for this example)
|
||||
|
||||
2 - Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
|
||||
version into the bin folder above (D:\Dev-Cpp\bin). The reason being is that
|
||||
the make.exe file resides in this folder. Make.exe will use - Makefile.m32,
|
||||
Makefile.inc, and the source code included in the lib folder to compile the
|
||||
source code. There is a PATH issue with make.exe that remains unresolved at
|
||||
least for me. Unless the entire source code to be compiled is placed entirely
|
||||
within the directory of make.exe an error message will be generated - "file
|
||||
xxxx.yyy not available".
|
||||
|
||||
3- Go to Dev-Cpp\bin and double click on make .exe. You will see a DOS window
|
||||
quickly pop up and close very quickly. Not to worry! Please do not skip this
|
||||
step.
|
||||
|
||||
4- Click on the start button\Programs\MS-DOS Prompt.Once the DOS Window is up
|
||||
Type the disk drive letter (e.g. E: ) engage the enter button. The path should
|
||||
automatically take you to the directory of the make.exe file.
|
||||
|
||||
5- To compile the source code simply type at the DOS prompt make -f
|
||||
Makefile.m32 as per instructions contained in the Makefile.m32 file (use any
|
||||
text processor to read instructions). I don't believe that this makefile
|
||||
allows for the option of non SSL. Ignore any warnings.
|
||||
|
||||
6- Collect and make copies of libcurl.a, libcurl.dll, libcurldll.a and any *.o
|
||||
compilations you might need in another directory outside of the bin directory
|
||||
as you will need this files shortly to set up libcurl for use with
|
||||
Dev-cpp. For most apps *.o is not required. Later on we will show what to do
|
||||
with these files.
|
||||
|
||||
7- You are finished but before closing we need to do cleanup - erase the bin
|
||||
folder and rename the "bin Original" folder created in step 1 to bin.
|
||||
|
||||
Note to compile a curl executable the process is probably similar but instead
|
||||
of using the LIB folder contents use the SRC folder contents and Makefiles in
|
||||
curl-7.14.0.tar.gz. File directories relative placements must be respected for
|
||||
compiling to take place successfully. This may not be possible with the PATH
|
||||
problem that make.exe experiences. If anyone has solved this PATH issue and
|
||||
please make sure it actually works on Win 9x/2000/XP before letting me
|
||||
know. Then please let me or Daniel in on the solution so that it can be
|
||||
included with these instructions. Thanks.
|
||||
|
||||
or
|
||||
|
||||
Method II - Dev-Cpp GUI
|
||||
-----------------------
|
||||
|
||||
1- Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
|
||||
version into any folder outside of (Dev-Cpp\bin).
|
||||
|
||||
2- Drop the File/New/click on Project.
|
||||
|
||||
3- New Project Dialogue box appears. Double click on the Static Library.
|
||||
|
||||
4- Create Project Dialogue box appears. Select the LIB folder location to
|
||||
place and locate your Project File Name. Placing the Project File Name
|
||||
elsewhere may cause problems (PATH issue problem again).
|
||||
|
||||
5- Drop down the Project/Project Options. Project Options Dialogue box
|
||||
appears.
|
||||
|
||||
6- Select the Makefile tab in the Project Options Dialogue Box. Check Box -
|
||||
Use Custom Makefile. Click on the Folder icon at the extreme right of the
|
||||
Check Box. Select Makefile.m32 in the folder wherever you have placed the
|
||||
contents of the LIB Folder. Press OK and close the Dialogue Box.
|
||||
|
||||
7- Drop the Menu Project/Click on Add to Project. Open File Dialogue Box
|
||||
appears. The Dialogue Box should open in the folder wherever you have placed
|
||||
the contents of the LIB Folder. If not go there.
|
||||
|
||||
8- Select Crtl-A to select all files in the LIB folder. Click on open to add
|
||||
files and close box. Wait till all files are added. This may take 30 seconds
|
||||
or longer.
|
||||
|
||||
9- Drop the Menu Execute/Click on Compile.
|
||||
|
||||
10- That's it.
|
||||
|
||||
|
||||
The following steps must be completed if Curl is to work properly
|
||||
=================================================================
|
||||
|
||||
LIB folder inclusions (*.a placement)
|
||||
-------------------------------------
|
||||
|
||||
1- Refer to Method I - DOS Command Line point # 6 Take libcurl.a, libcurldll.a
|
||||
and install it in the directory C( or whichever drive Dev is installed)
|
||||
:\Dev-Cpp\lib.
|
||||
|
||||
|
||||
Include Folder
|
||||
--------------
|
||||
|
||||
1- Create a new folder by the name of curl (do not change the name curl to
|
||||
some other name as it will cause major issues) in the directory
|
||||
C:\Dev-Cpp\include.
|
||||
|
||||
2- Copy the entire contents of the curl folder of curl-7.14.0.tar.gz or zip
|
||||
version into the newly created curl directory - C:\Dev-Cpp\include\curl.
|
||||
|
||||
Links To Include And Lib Folder
|
||||
-------------------------------
|
||||
|
||||
1- Drop the Menu - Tools\Compiler Options\Directories\Libraries. Make sure
|
||||
that C( or whichever drive Dev is installed):\DEV-CPP\lib is included.
|
||||
|
||||
2- Next select the Menu - Tools\Compiler Options\Directories\C Includes. Make
|
||||
sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are included.
|
||||
|
||||
3- Next select the Menu - Tools\Compiler Options\Directories\C++
|
||||
Includes. Make sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are
|
||||
included.
|
||||
|
||||
Linker Links
|
||||
------------
|
||||
|
||||
1- Drop the Menu - Tools\Compiler Options\Directories\Compiler.
|
||||
|
||||
2- Make sure that the box "Add these commands to the linker command line" is
|
||||
checked.
|
||||
|
||||
3- Include in the white space immediately below the box referred in 2 -lcurl
|
||||
-lws2_32 -lwinmm.
|
||||
|
||||
SSL Files
|
||||
---------
|
||||
|
||||
1- Get the latest openSSL (as of time of this writing)
|
||||
openssl-0.9.7e-win32-bin.zip for the minimalist package of the openssl-0.9.7e
|
||||
binaries ported to MS Windows 95/98/NT/XP using the MingW32/GCC-3.1
|
||||
development environment. The file may be downloaded at
|
||||
http://curl.haxx.se/download/.
|
||||
|
||||
2- Open the above zip file. You will find two files - SDL.dll,
|
||||
SDL_mixer.dll. Install them in the directory C:\WINDOWS\SYSTEM32 for Win 9x
|
||||
users and c:\winnt\system32 for NT-family users.
|
||||
|
||||
Multithreading Files
|
||||
--------------------
|
||||
|
||||
To be completed
|
||||
|
||||
#define
|
||||
-------
|
||||
|
||||
1- Make sure that your program includes the following - #define CURL_STATICLIB
|
||||
must be declared FIRST before any other define functions may be
|
||||
added. Otherwise you may experience link errors.
|
||||
|
||||
2- Don't forget to include #include "curl/curl.h".
|
||||
|
||||
e.g.
|
||||
#define CURL_STATICLIB
|
||||
#include <windows.h>
|
||||
#include "curl/curl.h"
|
||||
#include <fstream>
|
||||
#include <iostream>
|
||||
#include <vector>
|
||||
etc...
|
||||
|
||||
|
||||
Static or Dynamic Library
|
||||
-------------------------
|
||||
|
||||
The above steps apply for the use by a static library. Should you choose to
|
||||
use a dynamic library you will be required to perform these additional steps.
|
||||
|
||||
1- Refer to Method I - DOS Command Line point # 6. Install libcurl.dll in the
|
||||
directory C:\WINDOWS\SYSTEM32 for Win 9x users and c:\winnt\system32 for
|
||||
NT-family users.
|
||||
|
||||
2- Refer to Linker Links point 3 - Replace -lcurl with -lcurldll.
|
||||
|
||||
Voila you're done.
|
||||
|
||||
The non-SSL static Library build may not be possible to use at least as of the
|
||||
time of this writing - v7.14. Check reference emails - Phillipe and I found it
|
||||
impossible to fully compile as certain files were missing for linking. No big
|
||||
loss as SSL is a major plus.
|
||||
|
||||
Hope this Helps
