Thank you for the pointer. I wasn't aware of it and haven't entirely understood it yet. However, when I said 'for custom libraries installed by my project' I was not referring to cmake-based projects. These libraries are used as is and for the moment I don't want to integrate them via ExternalProject. -- Patrick. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

[CMake] best way of parsing test results from ctest + valgrind
Hello, I am just getting started on using valgrind memory analysis for my tests. When I run ctest with nightly memory check, I get an XML document, but it is very hard to read the results. What is the best way of reading this doc? Thanks!

Re: [CMake] CMAKE_DL_LIBS
Thanks! I found the problem: I needed to add CMAKE_DL_LIBS to another
static library that the main exe was linking to.
Now this link error is gone.

Re: [CMake] CMAKE_DL_LIBS
That link looks fine to me. You might want to verify that the CMAKE_DL_LIBS
variable actually contains what it should on your system (or a least
contains what it should right before using it).
You could explicitly add the "-dl" to that link statement and see if that
works. That's what that variable should contain anyways on Linux boxes.
-Caleb
(Pasting off list response below)
Thanks, Caleb. Are you saying that I need to add "-ldl" link lib in
addition to ${CMAKE_DL_LIBS} ?
My CMake file is here:
https://github.com/GrokImageCompression/opendcp/blob/master/cli/CMakeLists.txt
and the lines for the exe that is not linking are found here:
TARGET_LINK_LIBRARIES(opendcp_j2k ${CMAKE_DL_LIBS} ${OPENDCP_LIB} )
This is an open source proj, by the way. I can send you a few short lines
about how to build on Ubuntu, if you are interested.
Thanks very much for your help.

Re: [CMake] CMAKE_DL_LIBS
Most likely solution: missing the "-ldl" link lib which should solve
your missing symbol issues.
The DSO error is most likely caused by the above. However, there could be a
problem with your linking order. I'd have to see the CMake file to be sure.

[CMake] CMAKE_DL_LIBS
Hello!
I have a CMAKE project that creates an executable that links with a static
lib
from a second CMAKE project. The static lib requires the dlopen and dlclose
symbols.
So, when I link the first project, I add ${CMAKE_DL_LIBS} to the CMake file.
However, I still get an error about "undefined reference to symbol
"dlclose"
I am using CMake 3.2.2.
Any ideas ?
Thanks,
Aaron

The error states: "missing DSO from command line"
Also, the second CMAKE project also contains executables that link with the
static
library, and they link with no problem.
