ah
well the patches are from here and mostly unmodified
http://code.google.com/p/ccache-win32/issues/listthis is actually a win32 ccache but a few of the preprocessor variables where missing in the makefile so easy to fix
basically it just adding -DHAVE_STRING_H -DHAVE_CTYPE_H -DHAVE_STDLIB_H -DHAVE_GETHOSTNAME and then adding ws2_32 to the libraries to link with
theres two versions of the patch to this function (static void failed(void))
the working one is this one
#ifdef _WIN32
{
PROCESS_INFORMATION pinfo;
STARTUPINFO sinfo;
BOOL ret;
DWORD exitcode;
char *args;
extern char *argvtos(char **argv);
ZeroMemory(&pinfo, sizeof(PROCESS_INFORMATION));
ZeroMemory(&sinfo, sizeof(STARTUPINFO));
sinfo.cb = sizeof(STARTUPINFO);
sinfo.hStdError = GetStdHandle(STD_ERROR_HANDLE);
sinfo.hStdOutput = GetStdHandle(STD_OUTPUT_HANDLE);
sinfo.hStdInput = GetStdHandle(STD_INPUT_HANDLE);
sinfo.dwFlags |= STARTF_USESTDHANDLES;
args = argvtos(orig_args->argv);
ret = CreateProcessA(orig_args->argv[0], args, NULL, NULL, TRUE, 0, NULL, NULL, &sinfo, &pinfo);
free(args);
if (ret == 0)
{
cc_log("CreateProcessA failed\n");
exit(1);
}
WaitForSingleObject(pinfo.hProcess, INFINITE);
GetExitCodeProcess(pinfo.hProcess, &exitcode);
CloseHandle(pinfo.hProcess);
CloseHandle(pinfo.hThread);
exit(exitcode);
}
#else
execv(orig_args->argv[0], orig_args->argv);
cc_log("execv returned (%s)!\n", strerror(errno));
perror(orig_args->argv[0]);
exit(1);
#endif
the other uses a hacky mingw implementation that doesnt quite work.
full function below for visibility.
