Re: [Openexr-devel] .la and link to basename .so

[Charles Flèche]

My current interest is to have a working PyIlmBase. I've forked the git 
repo to https://github.com/charlesfleche/openexr

The patches in the develop branch implement some CMakeLists.txt for 
IlmBase and PyIlmBase. Building these two subprojects with cmake yields 
the same artifacts than with autotools, with the following differences :

1. there are no .la files
2. I've only tried to build shared libs so far, and only under Linux
3. there are no links from libName.so -> libName-2_0.so for the time being
4. so of course the package config files use the *-2_0 lib names
5. as I haven't started working on the OpenEXR subproject, 
PyIlmBaseConfig.h is not generated (according to the docstring this one 
is only useful for a IlmImf test)

To build IlmBase and PyIlmBase with CMake, I define CMAKE_INSTALL_PREFIX 
and BUILD_SHARED_LIBS

$ git https://github.com/charlesfleche/openexr.git
[then switch to branch develop]
$ cd openexr
$ mkdir IlmBase-build
$ cd IlmBase-build
$ cmake ../openexr-src-git/PyIlmBase 
-DCMAKE_INSTALL_PREFIX=/home/charles/src/openexr-install-git 
-DBUILD_SHARED_LIBS=true
$ make VERBOSE=1
$ make install

(same for PyIlmBase)


You can also run the tests with "make test". A few tests won't pass :
1. in PyImathTest, the function noiseCen is called but defined nowhere
2. in PyImathNumpyTest, the module boostutil doesn't exist hence can not 
be imported
