[Clam-devel] Troubleshooting

[David García Garzón]

You can not take config.h files from upstream source tarball and expect them 
to work since they are generated files for a concrete platform, and for sure 
the ones in the upstream source tarball were generated for linux or similar, 
so nothing will work.

The big precompiled 3rd party tarball in clam web provides properly generated 
config.h files for windows. Although it is true that those special headers are 
not in local/include, they are at local/lib/include, and there is nothing 
wrong with that: pkg-config tool properly sets the include path to point on 
both of them. So i guess that there is some problem with the pkg-config 
execution, if so, even by getting the config.h files to work you will have 
more problems than that. So let's check what's happening with pkg-config.

To check whether each try works or not you should be able to get the needed 
options when you issue on the following command on the msys console:
	pkg-config --cflags --libs libxml++-2.6

If a 'command not found' error is shown, then you should check that the pkg-
config.exe file is in one of the path displayed on:
	echo $PATH
if not just append this line in MSYS/etc/profile
	export PATH="C:\MinGW\local\bin":$PATH
I guess that it should'nt be needed as the wiki doesn't mention it. If so, 
warn us.

If you get a 'No package found' error instead, then the problem is that pkg-
config cannot locate the pc files in C:\MinGW\local\lib\pkgconfig. Check that 
the pc files are in there and that you appended the following line in the 
MSYS/etc/profile file as the wiki says:
	export PKG_CONFIG_PATH="C:\MinGW\local\lib\pkgconfig"

If the standalone pkg-config command worked then it may happen that you failed 
to provide the sandbox_path option properly on the 'scons configure' command. 
I don't have any other reason for it to fail. Did we got it? If not, please, 
send us the output of the pkg-config command or the config.log file.

David.
