[Tinycc-devel] libtcc.dll

I have been able to create a libtcc.dll for WinXP using MinGW/MSYS;
the changes that were necessary were very minor. Perhaps this
description will help others use libtcc on Windows.

First, a small bug to report:

In tcc.c the function tcc_basename() follows the line:

#if !defined(LIBTCC)

but the function tcc_basename() is used in pe_build_exports() in
tccpe.c -- moving the #if line below the function tcc_basename()
eliminates a link error building libtcc.dll in PE target mode.

Second, configuring and making tcc with MSYS places a pathname in
config.h in MSYS format. For example, I passed the argument


to configure; this path was good for building tcc.exe and didn't
contain any spaces, unlike the default path. This creates the line

#define CONFIG_TCCDIR "/c/Dev/tcc"

in config.h. Manually changing this line to

#define CONFIG_TCCDIR "C:/Dev/tcc"

enables libtcc.dll to find the include files and libraries once the
library is built. [The application tcc.exe avoids this problem by
setting tcc_lib_path from the application's directory at startup. A
similar solution could be used for the library using DllMain.]

So, after configure, fix CONFIG_TCCDIR in config.h and make.

Finally, the library libtcc.dll can be built with the MSYS command:

gcc -O2 -shared -Wall -Wl,--export-all-symbols \
-mpreferred-stack-boundary=2 \
-march=i386 -falign-functions=0 -fno-strict-aliasing \
-DTCC_TARGET_PE -DLIBTCC -o libtcc.dll tcc.c
