How to Build cURL and use it in a Code::Blocks pro

Question

I know there are many topics about this but none of them helped me to solve my problem. All I want is to make a simple C++ program that uses cURL with static libcurl (without DLL files) on Code::Blocks - Windows 8. I've spent around 20 hours trying to do this but all I found is unuseful stuff and stuff I don't understand.

After downloading curl-7.39.0.zip from http://curl.haxx.se/download.html and extracting it to my Code::Block directory, I ran Developer Command Prompt for VS2013 as Administrator and entered the following:

cd C:\Program Files (x86)\CodeBlocks\curl-7.39.0\winbuild
nmake /f Makefile.vc mode=static vc=12 debug=no

The output of the second command was: http://pastebin.com/bwPqxp9V

Then I made a new empty Code::Blocks project with Main.cpp:

#include <curl/curl.h>
int main() { curl_global_cleanup(); }

In Code::Blocks, I navigated to Project > Build Options
In Compiler Settings > Defines, I added CURL_STATICLIB
In Linker Settings > Link Libraries, I added the path of the .lib file generated (which exists):

..\..\..\..\Program Files (x86)\CodeBlocks\curl-7.39.0\builds\libcurl-vc12-x86-release-static-ipv6-sspi-winssl\lib\libcurl_a.lib

In Linker Settings > Other Link Options, I added -static
In Search Directories > Compiler, I added:

..\..\..\..\Program Files (x86)\CodeBlocks\curl-7.39.0\builds\libcurl-vc12-x86-release-static-ipv6-sspi-winssl\include

I may have edited some other stuff, but nothing important.
When I build using GNU GCC Compiler with the following command:

mingw32-g++.exe  -o Debug\MyTestProgram.exe Debug\Main.o  -static  "..\..\..\..\Program Files (x86)\CodeBlocks\curl-7.39.0\builds\libcurl-vc12-x86-release-static-ipv6-sspi-winssl\lib\libcurl_a.lib"

I get 80 warnings similar to:

.drectve `/DEFAULTLIB:"MSVCRT" /DEFAULTLIB:"OLDNAMES" ' unrecognized

And more than 50 errors. What I did wrong and how can I fix it?
Feel free to ask me for more details if needed.

Answer 1

Intro:

To build libcurl with gcc on windows, you need a command line tool. You may use Git-Bash or MSYS. Your choice.

• I'll be using MSYS: MSYS1.0.11.
• I'll be using Mingw: Mingw 4.8.1-rev5.7-sjlj-posix-threads
• I'll be building Curl: Curl-7.39.0.

---

Getting Started:

Start the MSYS installation. Choose whatever folder you like for the installation. When the command-line window pops up, answer as follows:

---

PRE-SETUP:

Now you have a command-line tool "make" installed and is compatible with your gcc/g++/mingw.

BEFORE we run the commands, there's a few things you need to know:

• If using 32-bit gcc/g++ then change to: --build=i686-pc-mingw32.

• If using 64-bit gcc/g++ then change to: --build=x86_64-w64-mingw32.

• If using SSL, change --without-ssl to --with-ssl and add -DOPENSSL_PATH=Path_To_Open_SSL_Here.

• If you need to specify a special path to your ZLIB then add -DZLIB_PATH=Path_To_ZLib_Here.

• If you want to build STATIC then use --disable-shared otherwise don't use it OR use --enable-shared.

---

Configuration:

Open MSYS.bat and run the following commands (modify as needed and described above):

$ cd "C:/Users/USERNAME/Desktop/curl-7.39.0"

$ ./configure --prefix=/usr/local --without-ssl --disable-shared --build=x86_64-w64-mingw32 CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib"

It should start doing a bunch of "checks". It will take a while so go get a coffee or something. If all is well and the configuration is complete, and you have everything setup correctly, then you should see the following:

---

Building & Installing:

Finally, run the following commands:

$ make install-strip

It should now start building and it will install to (Wherever your MSYS installation is -- Mine is C:/Msys):

 C:/Msys/1.0/local/bin
 C:/Msys/1.0/local/include
 C:/Msys/1.0/local/lib

Those locations should have all the files necessary for you to use libcurl with gcc/g++/mingw.

If all went well, it will look like:

---

OPTIONAL:

• You may either link to them in that location or move them.
• You can copy the files in "include", "lib" and "bin", into your mingw installation folder respectively (include + curl-folder to include, bin to bin, lib + package-folder to lib).
