Hello,
I would like to compile a C++ code to be executed within the linux
emulator.
I tried to install the cross-gcc port, but when building I always receive the
same
compilation error related to gthreads.
I use the following options when compiling the cross-gcc port:
make TGTARCH=i386 TGTABI=linux install clean
I also tried several combinations like "i386-pc" and "linux-gnu".
When building, I get the following error message:
