it looks more straightforward now, even -ui is gone :)
but there's still something wrong...
$ cmake --version
cmake version 2.8.12.1
$ mkdir cmake_build; cd cmake_build
$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/tmp/cgc ..
$ make
first, the situation before "make install".
$ chrpath main/gnucap
main/gnucap: RPATH=/home/felix/extern/gnucap-upstream/cmake_build/lib:
this looks good, apparently cmake knows that gnucap is linked against
something within lib/*
$ chrpath lib/libgnucap.so
lib/libgnucap.so: no rpath or runpath tag found.
this is suboptimal, libgnucap.so should know where to load plugins from.
as a consequence, i get
$ main/gnucap
[..]
load libgnucap-default-plugins.so
^ ? libgnucap-default-plugins.so: cannot open shared object file:
[..]
it's important that gnucap ran-from-builddir explicitly and forcefully
picks up plugins from builddir (by default). anything else will cause
trouble.
now the situation after "make install", prefix is /tmp/cgc.
$ chrpath /tmp/cgc/bin/gnucap
/tmp/cgc/bin/gnucap: no rpath or runpath tag found.
suboptimal and gives
$ ldd /tmp/cgc/bin/gnucap
linux-vdso.so.1 (0x00007fff82bff000)
libgnucap.so => not found
[..]
and
$ chrpath /tmp/cgc/lib/x86_64-linux-gnu/libgnucap.so
/tmp/cgc/lib/x86_64-linux-gnu/libgnucap.so: no rpath or runpath tag found.
is suboptimal, leads to
$ LD_LIBRARY_PATH=/tmp/cgc/lib/x86_64-linux-gnu /tmp/cgc/bin/gnucap
[..]
load libgnucap-default-plugins.so
^ ? libgnucap-default-plugins.so: cannot open shared object file: No such
file or directory
[..]
as it seems, automake adds more runpaths by default. but not all.
particularly i had to add RUNPATH for libgnucap.so manually. somehow
this makes sense, as long as the build system does not know about
plugins and what is supposed to dlopen them. i am curious if cmake has
better support for this.
cheers
