Somewhere between change set  http://hg.octave.org/mxe-octave/rev/076acecb9c21   and changeset http://hg.octave.org/mxe-octave/rev/21586f2d1fe7, Qt in the native build started failing in its build.

 

 

Do you have an error log about why libmng is not compiled? (assuming it is actually not compiled, but the error above seems to go in that direction). In those 2 changesets, the only change that could be suspicious is the addition of CC='$(MXE_CC)' to zlib.mk, though I don't see at the moment how it could affect a native MinGW build.

So it is changeset http://hg.octave.org/mxe-octave/rev/d89eccc2edd3  that causes it to fail.

 

There are 2 changes to zlib in that change set, the first being the removal of CC=MXE_CC. the second being that it doesn’t install the static libraries unless selected to do so.

 

I tried removing the CC part, so am guessing libmng is using the static zlib for some reason.

 

I was looking at your previous mail, and it appears libmng also installs the static library (though it shouldn't if --enable-static is not specified). So maybe what's happening is that Qt is using the static libmng, but fails to do so because it requires the static zlib. If I'm right, then the "solution" would be not to install the static version of libmng.

 

Michael.

 

 

Can it be set to use the ENABLE_SHARED_OR_STATIC?

 

 

The configure script of zlib is non-standard and does not support the --enable/disable-static/shared. AFAICS, it only supports --enable-shared.

 

Michael.

 

 

Ok

I notice also that we now do not install the zlib.pc, zlib.h and zconf.h files if not installing the static version of zlib

Obviously, that was not intended, sorry. I didn't notice, because those files got installed from an earlier attempt. I guess the target "install" should then be called unconditionally. Though I may not have the time to fix that before Monday.
