Duby/Capstone

Capstone Engine is an open source library for disassembly.

Compiling with Mingw (32 or 64)

The default compilation doesn't work and fails with a linking error:

./arch/Sparc/SparcInstPrinter.o:SparcInstPrinter.c:(.text+0x4e0): multiple definition of `imaxabs'
./arch/PowerPC/PPCInstPrinter.o:PPCInstPrinter.c:(.text+0x16030): first defined here
collect2.exe: error: ld returned 1 exit status
make: *** [libcapstone.so] Error 1

(for whatever reason "imaxabs" is included in resulting files as a stand-alone function, rather than inline function)

The following command line should be used to compile the library on MinGW (with gcc installed)

CFLAGS="-llibmingwex" ./make.sh gcc

Adding libmingwex library for compilation prevents imaxabs to be inserted into .o file (because the function is implemented in mingwex)

For x64, there's Mingw-64 project.

Static Linking

Once the static library is built, it's possible to link it statically to the executable. However, there are certain dependencies that must be resolved first.

 {$linklib libcapstone} // library itself
 {$ifdef mswindows}
 {$linklib libmsvcrt}   // MS Visual C runtime (mingw bindings)
 {$linklib libgcc}      // C++ library
 {$endif}

• libmsvcrt for _malloc _calloc _realloc _free _vsnprintf _memset _memcpy _strncpy _sprintf _strlen _strrchr _strncmp _strstr _strcmp _strchr _memmove _strcpy _atoi _tolower
• libgcc for ___ctzdi2 ___popcountsi2 ___popcountdi2 ___umoddi3 ___udivdi3 (https://gcc.gnu.org/onlinedocs/gccint/Integer-library-routines.html)

Such dependencies are pretty typical for mingw compilation.
