MINGW64 : undefined symbol in libsystemc.a

[JIBI3731]

Dear fellows,

I just downloaded systemc2.3.3  and when i generate the test  exe (using make check) i get  an error  at link :

undefined symbol in libsystemc.a(sc_simcontext.o):sc_simcontext.cpp:(.text+0x6704): undefined reference to `sc_core::sc_cor_pkg_qt::sc_cor_pkg_qt

 

i had no problem to build  the libs (libsystemc.a , libsysc.a, libtlm_core.a and libtlm_utils.a) but apparetnly the libsystemc.a  contains unresolved reference ? 

i use  MSYS2 with mingw64  and before building, i set the CXXFLAGS  variable : 

CXXFLAGS='-O3 -g -Wall -Wextra -Winvalid-pch -Wno-unused-parameter --std=gnu++11'
 

Please help me , i'm stuck 😞

Thanks in advance

Best regards

JB

Building SystemC using G++ from MSYS2/MinGW-64 should work as described in the INSTALL file. To diagnose your problem, it would help if you could provide all commands, which you used to configure and build SystemC 2.3.3 and then to run the tests. Please, also provide the log file generated by configure. Did you observe any errors/warnings during the compilation of the SystemC library? You should pass in the CXXFLAGS to your configure call as described in the INSTALL file, section "SystemC Library Configuration Switches":

../configure CXXFLAGS="-DSC_OVERRIDE_DEFAULT_STACK_SIZE=0x80000"

You can also try to build SystemC with the latest fixes released in its official public Git repository. You can also try to build SystemC from that repository using CMake as described in cmake/INSTALL_USING_CMAKE.

Hi,

I made the following : 

./configure --target=mingw64  CXXFLAGS="-DSC_OVERRIDE_DEFAULT_STACK_SIZE=0x80000"

then : 

make : OK , no compilation error error 

and then : 

make check : i get the following :

I also atatched the config.log 

Many thanks for the support

Actually, it is expected that you don't have the QuickThreads package built on MinGW.  As you can see from your config.log, the threading package to use is

Quote

---------------------------------------------------------------------
Configuration summary of SystemC 2.3.3 for x86_64-pc-mingw64
---------------------------------------------------------------------

...

 Build settings:
   Enable compiler optimizations  : yes
   Include debugging symbols      : no
   Coroutine package for processes: WinFiber
   Enable VCD scopes by default   : yes
   Disable async_request_update   : no
   Phase callbacks (experimental) : no
--------------------------------------------------------------------

But it seems that the source code is missing an explicit check for _WIN64 to catch the MinGW-64 case. Can you try compiling with WIN64 defined (without leading underscore):

../configure CXXFLAGS="-DWIN64"

Hope that helps,
  Philipp

Thanks Philipp

I tried :  ../configure CXXFLAGS="-DWIN64" --target=mingw64

but i get an error , early at compile  time : 

make[3] : on entre dans le répertoire « /d/BOULOT/tools/SYSTEMC/NEW2/systemc-2.3.3/objdir/src/sysc »
  CXX      kernel/sc_attribute.lo

       PVOID cur_fiber = GetCurrentFiber();
       ^~~~~
../../../src/sysc/kernel/sc_cor_fiber.cpp:73:22: error: 'cur_fiber' was not declared in this scope
       if( m_fiber != cur_fiber && this != m_pkg->get_main() )

and then other errors in cascade .....

 

The missing PVOID is a declaration i think in <windows.h> ?????? 

I keep searching ....

Hi all

I finally decided to go with cygwin and it worked at once, without problem

the main difference i could notice is the choice of the  library for threading  (qt vs fiber)
