[CMake] Compilation with multiple jobs fails

Hi,
I'm trying to compile a custom library using CMake code. The
configuration and compilation goes well when I just use 'make'. In
order to speed things up I tried to compile the library with multiple
jobs in parallel with 'make -j2'. However, compilation always fails in
that case (tested on multiple computers (Fedora - Ubuntu x86_64)). I'm
using cmake 2.8.0. I'v emailed this to the developers of the library
as well (see emails below). The piece of cmake code involved is
indicated below as well, but I'll repeat it here for clarity:
The error I get:
-----------------------------------------------------------
"Generating dyncall-0.3/ConfigVars
* configure package dyncall
guess operating system linux
guess arch x64
guess tool gcc
guess assembler as
[ 2%] Generating dyncall/lib/libdyncall_s.a, dyncall/lib/libdynload_s.a
make[3]: Leaving directory
`/home/steven/src/svn/cturtle/install/stacks/kul-ros-pkg/stacks/orocos_toolchain_ros/typelib/build'

make[4]: *** read jobs pipe: Is a directory. Stop.
make[4]: *** Waiting for unfinished jobs...."
----------------------------------------------------------------
And the corresponding cmake code:
-----------------------------------------------------------
ADD_CUSTOM_COMMAND(OUTPUT ${DYNCALL_SOURCE_DIR}/ConfigVars
COMMAND tar xzf ${CMAKE_CURRENT_SOURCE_DIR}/dyncall-0.3.tar.gz
COMMAND cd ${DYNCALL_SOURCE_DIR}
&& ./configure --prefix=${DYNCALL_INSTALL_DIR}
DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/dyncall-0.3.tar.gz)
ADD_CUSTOM_COMMAND(OUTPUT ${DYNCALL_LIBRARIES}
COMMAND make "CFLAGS=-O3 -fPIC"
COMMAND make install
DEPENDS ${DYNCALL_SOURCE_DIR}/ConfigVars
WORKING_DIRECTORY ${DYNCALL_SOURCE_DIR})
ADD_CUSTOM_TARGET(dyncall DEPENDS ${DYNCALL_LIBRARIES})
-----------------------------------------------------------
I'm not that of a cmake expert, but I see that dyncall needs DYNCALL_LIBRARIES,
DYNCALL_LIBRARIES depends on ConfigVars,
and ConfigVars are created with the custom command
Any ideas what goes wrong here?
best regards,
Steven

looking on the code, I have found the dependencies in the custom commands.
-----------------------------------------------------------
ADD_CUSTOM_COMMAND(OUTPUT ${DYNCALL_SOURCE_DIR}/ConfigVars
COMMAND tar xzf ${CMAKE_CURRENT_SOURCE_DIR}/dyncall-0.3.tar.gz
COMMAND cd ${DYNCALL_SOURCE_DIR}
&& ./configure --prefix=${DYNCALL_INSTALL_DIR}
DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/dyncall-0.3.tar.gz)
ADD_CUSTOM_COMMAND(OUTPUT ${DYNCALL_LIBRARIES}
COMMAND make "CFLAGS=-O3 -fPIC"
COMMAND make install
DEPENDS ${DYNCALL_SOURCE_DIR}/ConfigVars
WORKING_DIRECTORY ${DYNCALL_SOURCE_DIR})
ADD_CUSTOM_TARGET(dyncall DEPENDS ${DYNCALL_LIBRARIES})
-----------------------------------------------------------
I understand that to build dyncall needs DYNCALL_LIBRARIES:
- DYNCALL_LIBRARIES depends on ConfigVars
- and ConfigVars are created with the custom command _after_ tar and after the
configure step (configure creates the ConfigVars file)
So, I don't see any clear error here. Maybe is a cmake bug ....
