I replicated your cmake.out with the following cmake options.
cmake -DCMAKE_INSTALL_PREFIX=/home/software/plplot_cvs/installcmake
-DENABLE_DYNDRIVERS=OFF -DDEFAULT_NO_BINDINGS=ON -DDEFAULT_NO_DEVICES=ON
-DPLD_ps=ON ../plplot_cmake >& cmake.out
Do you confirm those? I am pretty amazed you are getting a segfault for
such a simplified build.
After my make install I changed to the installed examples tree and did
the exact commands you did above with no segfault. I then applied valgrind
and got a perfect result. So I am having extraordinary trouble replicating
the segfault that you are seeing for virtually an identical platform
(both tests were for 64-bit hardware using the same [except
for presumably small distro patches] compiler version).
Could you try again with the same cmake options as above except for the
install prefix? As I told you off list, make sure you have a clean source
tree and an initially empty build tree and install tree. Also use VERBOSE=1
for the make commands (e.g., make VERBOSE=1 and make VERBOSE=1 install) to
make their output useful and comparable to mine. While in the installed
examples/c directory could you also output the result of the pkg-config
command that is in the Makefile? For me I have
PKG_CONFIG_ENV = \
PKG_CONFIG_PATH=/home/software/plplot_cvs/installcmake/lib/pkgconfig
so pkg-config is run as follows:
PKG_CONFIG_PATH=/home/software/plplot_cvs/installcmake/lib/pkgconfig \
pkg-config --cflags --libs plplotd
The result for my platform is
-I/home/software/plplot_cvs/installcmake/include/plplot
-L/home/software/plplot_cvs/installcmake/lib -lplplotd -lm -lcsirocsa
-lcsironn -lqhull -lfreetype
The resulting ldd -r results are as follows:
softw...@raven> ldd -r ./x21c
linux-vdso.so.1 => (0x00007ffff11ff000)
libplplotd.so.9 =>
/home/software/plplot_cvs/installcmake/lib/libplplotd.so.9 (0x00007f02e8d03000)
libm.so.6 => /lib/libm.so.6 (0x00007f02e8a80000)
libcsirocsa.so.0 =>
/home/software/plplot_cvs/installcmake/lib/libcsirocsa.so.0 (0x00007f02e8877000)
libcsironn.so.0 =>

libc.so.6 => /lib/libc.so.6 (0x00007f02e7e42000)
libz.so.1 => /usr/lib/libz.so.1 (0x00007f02e7c2b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f02e8f72000)
What are your equivalent results?
Could others here also try the same simplified build to see if they
can replicate the segfault found by Hazen? I am completely stumped as
to how to reproduce this.
