wxwidget build failed - windows - mingw - mingw32-make: *** [..\..\lib\gcc_dll\wxmsw313u_gcc_custom.dll] Error 1 - wxwidgets

Question

I was trying use build wxWidgets-3.1.3 with MinGW-W64 on a x64 windows machine.
I followed this thread, which lead me to download and building. So I installed it and some youtube videos said I need to build it now. So navigate to the installed folder and gave this command :
mingw32-make -f makefile.gcc BUILD=release SHARED=1 MONOLITHIC=1 UNICODE=1.
It took almost half an hour and now it's giving me error saying :
collect2.exe: error: ld returned 1 exit status
makefile.gcc:5329: recipe for target '..\..\lib\gcc_dll\wxmsw313u_gcc_custom.dll' failed
mingw32-make: *** [..\..\lib\gcc_dll\wxmsw313u_gcc_custom.dll] Error 1
Here is the full log file :
https://pastebin.com/zxeHhF6K
MinGW configuration :
Version : 8.1.0
Architecture : x86_64
Threads : posix
Exceptions : seh
Build version : 0
How can I solve this? I'm using CLion, is there any other short or easy way?

Answer 1

The relevant error is
..\..\lib\gcc_dll/libwxexpat.a(wxexpat_xmlparse.o):xmlparse.c:(.text+0x337d): undefined reference to `_imp__rand_s'
and it's very strange because MinGW-w64 8.1 is definitely supposed to have rand_s(). Are you sure you're using the right compiler? I.e. what does g++ -v give you if you run it from the same command prompt?
My only hypothesis is that it's some different (and much older) compiler and the solution would be to just use the right one instead.
Also, the next time you could use -j4 option with make if you have at least 4 logical CPUs in your machine (and chances are you do nowadays), to significantly speed up the build.

Answer 2

Looking back in my notes I once had an issue with missing rand_s() when building glib2 on a certain MinGW build.
I was able to fix it then by adding this at the top of the C file that called this function:
#include <time.h>
#include <stdlib.h>
int rand_s (unsigned int* r)
{
static int srand_called = 0;
if (!srand_called) {
srand(time(0));
srand_called++;
}
if (r)
*r = rand();
return 0;
}
In your case that would be in xmlparse.c.
