Title: MinGW with STLport
Post by: alifehpp on February 03, 2007, 12:20:42 pm

I have problem using Code::Blocks with Mingw and STLport. A "hello, world" project doesn't link.
I try different settings of C::B but i have a linker errors
There is a code:

Code

#include <vector>
#include <string>
#include <iostream>
int main()
{
	std::vector<std::string> vec;
	vec.push_back("hello cb");
	std::cout << vec[0];
        return 0;
}

there are errors:

Code

F:/stlport/stlport/stl/_move_construct_fwk.h:104: undefined reference to `_imp___ZN11stlpmtx_std4coutE'
F:/stlport/stlport/stl/_move_construct_fwk.h:104: undefined reference to `_imp___ZN11stlpmtx_std12__node_alloc13_M_deallocateEPvj'
F:/stlport/stlport/stl/_move_construct_fwk.h:104: undefined reference to `_imp___ZN11stlpmtx_std8ios_base16_M_throw_failureEv'

collect2: ld returned 1 exit status

I have Mingw 3.4.5, C::b rev 3558 (31.01) and STLPort 5.1.0
P.S. Sorry for my English.

link with the STLport library
use multithreading by specifying -mthreads in "Build options => Compiler/Linker => Other Options"
don't forget, that if you use multithreading, your executable needs the mingwm10.dll, that is in your MinGW bin directory

Thank you very much, but solve this problem myself. But i have another question, does gcc support auto link?

I have downloaded new C::B build and application witch build within STLport fails with runtime error. SIGSEGV, Segmentation fault, what it means and how fix it?

Hello,

May be this website could help you:

http://en.wikipedia.org/wiki/Segmentation_fault

Also search with google for e.g., "SIGSEGV, Segmentation fault". You should find helpful information :).

Best wishes,

Thank you, under Visual Studio it called access violation. But why STLport fails under MinGW and not under VS8?
If not use iostreams, all works perfectly. I wonder.

Just my two cents worth. Reading or Writing to an unopened file can cause all sorts of faults.

Hello,

GCC and VS8 C++ are two different compilers more or less ISO C++ compliant.

Regarding your problem, did you check that everything is installed correctly (MinGW+binutil+win api, C::B, etc.)? Did you set the path to every include file and library in C::B?

You can try with a newer C::B revision...

Also give a try to a google search with "MinGW with STL Port". With a bit of luck, you should get helpful info.

Best wishes,
Michael

Did you copy the STL DLLs to the project folder that contains the exe?

Your test hello world worked for me with STLport STLport-5.0.3, note it did need the DLL for libstlport.5.0.dll to work. Below is my compile commands.
Note, the readme stated that STLport includes must before the normal includes.

Installed STLport-5.1.0 and it also worked.

I used MSys to build the libs and I used the commands below to compile the libs.

From the README file steps for GNU Make (Linux, OpenBSD, FreeBSD, CygWin, etc.), with gcc:

make -f gcc.mak depend
make -f gcc.mak install

Note, STLport-5.0.3 seems to work better than STLport-5.1.0.
