Subject: makefile, build (cygwin)
>From some testing I have done, there may be no reason at all for keeping the
PROJ_WIN32 stuff (only used in cygwin builds).
I have change to using the PROJ, and Cygwin builds just fine. It creates ln
-s files, each pointing to john. Yes, there is no extension in the symlink,
but it works perfectly (at least on my builds).
Also tested, a make clean, and everything got clean up just fine. I removed
the PROJ_WIN32, and PROJ_WIN32_MINGW from the rm -f make clean line, just to
check a few things out. All of the .exe files were properly removed on a
make clean. The exe files in the run dir were:
calc_stat.exe
genmkvpwd.exe
gpg2john.exe
john.exe
keystore2john.exe (was not being build using PROJ_WIN32, but IS part of
PROJ)
mkvcalcproba.exe
raw2dyna.exe
tgtsnarf.exe (was not being build using PROJ_WIN32)
truecrypt_volume2john.exe (was not being build using PROJ_WIN32)
uaf2john.exe (was not being build using PROJ_WIN32)
wpapcap2john
All of those files were getting cleaned up properly with make clean, even
without ../run/calc_stat.exe being on the rm -f line (../run/calc_stat was
on the rm -f line).
We might want to look at Cygwin requirements again. On my install, the
normal unix ln -s method, and lack of .exe was working just fine (i.e. the
PROJ rule only). Probably too late for J8, but should be on the radar for
later builds.
I do not have a buildable mingw environment anymore, so have no way of
knowing if the mingw requires the PROJ_WIN32_MINGW, but I imagine it does.
I do not think mingw would handle the .exe'less naming properly, and am not
sure if symlinks would work. Also, symlinking to john vs john.exe may not
work. I really do not have answers at this time.
The changes I made to the make file, were:
1. remove the PROJ_WIN32 (not needed)
2. change each Cygwin target to use $(PROJ) instead of $(PROJ_WIN32)
3. remove $(PROJ_WIN32) from the make clean
One thing I have disliked for a long time, is the Win32 symlink executable
program. Using a real symlink avoids some strange behavior, when it comes
to
Jim.
