I'm running linux with cmake 2.6.4, gcc 4.3,3. if mean that if I run cmake clean, then try to compile it when it
failes. here:
running project clean generates:

Looks like your dependencies aren't set up correctly. You probably need
something like:

add_dependencies (AgathaHud AgathaUtils)

The first run does eventually get around to creating libAgahtaUtils.so,
so AgathaHud can find it during the second run.

These problems are often easier to diagnose/find if you don't do
parallel builds (no -j flag to make).

I am glad that worked for you but something else is wrong...  How are 
you linking bin/libs/libAgathaUtils.so' to `bin/AgathaHud' ?  You should 
have something like:

target_link_libraries(AgathaHud AgathaUtils)

That should add the dependency for you.   Do you have that?

"No such file or directory" error when using cmake/swig

Hello,

I’m trying to use swig & cmake to generate java files for one of my libraries. The problem I’m having is that I’d like to create a jar from

the output file but I don’t know how to create a directory that swig can write to from Cmake. I’ve specified:

SET(CMAKE_SWIG_OUTDIR "${PROJECT_BINARY_DIR}/java/src/com/or/vtkormodelreader" )

In my cmake file but during compile I receive the following error:

Unable to open file E:/work/research/vtkORModelReader/build32/java/src/com/or/vtkormodelreader\vtkORModelReader.java: No such file or directory

3>Project : error PRJ0019: A tool returned an error code from "Swig source"

If I manually create the directory structure, it works perfectly, however this isn’t the desired behavior.

I thought I could work around this by creating the directory during the build but I can’t find any commands to do something similar to “mkdir”.

Am I going about this the wrong way?

Gerrick

The install() command

   http://www.cmake.org/cmake/help/cmake2.6docs.html#command:install

interprets relative DESTINATION paths with respect to the installation
prefix (CMAKE_INSTALL_PREFIX).  No other interpretation is supported.

Are you seeing special behavior for an App Bundle?  Did you set
the prefix to point inside an otherwise manually created bundle?

Look at cmake -E make_directory.

You can run that as part of your build process with either
execute_process() or, probably better, with an
add_custom_command()/add_custom_target() combo. See the FAQ for details.

You should use
add_custom_command(OUTPUT <fullpath>/foo.h
... )

and then list that generated file as a source file for your target:

add_library(blub <fullpath>/foo.h foo.c bar.c ...)

I know by this way, if foo.h is changed, blub will be rebuilt. But what I need is foo.h is guaranteed to be up to date before foo.o is built. I am not sure if this command is relevant to this. Will cmake try to make sure all the src files are up to date before compiling any .c files?

This should make sure that everything is up to date.

The header-file dependency scanning does in general not work for generated
files, you need to list the generated file as source file for the targets
which need it.

Another problem is that I am trying to avoid adding dependencies for these generated files manually because in my project, there are many generated head files and quite a few .c files including them. I just want to make sure the head files are generated before any .c compilation. ADD_CUSTOM_TARGET can do this but it will regenerate the head files even they are up-to-date.

I have this:

                                ${LIBRARY_OUTPUT_PATH}/libAgathaEngine.so
                                ${LIBRARY_OUTPUT_PATH}/libAgathaThreads.so

                                PocoXML
                                PocoFoundation

OK, that is not correct.  For targets that CMake builds, you can just 
use the target name.  What you have now will only work on some systems 
and not work if you use OUTPUT_NAME or other properties on those 
libraries.

You want:
target_link_libraries(AgathaHud AgathaUtils AgathaEntine AgathaThreads)

That is assuming that AgathaUtils AgathaEntine AgathaThreads are all 
built in the same project by CMake.
