Dear René,

Thanks for your suggestion. I will try it with cmake3.3

Meanwhile, I went to individual directories of ~/src/picongpu and compiled
individual modules cuda_memtest, mpiInfo etc. in that directory itself.

After that I commented the lines having add_subdirectory() function in
cuda_memtest and mpiInfo  module in the file
~/src/picongpu/src/piconpu/CMakeLists.text (line number 293 and 307)

Now, when I used

rm -fR ~/build && mkdir ~/build && cd ~/build
$PICSRC/configure ~/paramSets/case001
make -j install

It compiled and installed successfully. I am yet to test an example.
This is an issue with cmake  new version as mentioned in the link I have
given in my previous email.

Regards,
Ajit

Dear Ajit,

thank you for providing use with the link. We need to test cmake 3.5 with
PIConGPU.
Could you please install cmake 3.3 till we fix the issue.

best,

René

Dear Rene,

Here is a link that answers why the build directory error comes in
versions of cmake.

http://stackoverflow.com/questions/24739401/cmake-project-shared-depen
dencies

The error in my case is:

CMake Error at CMakeLists.txt:42 (add_subdirectory):
    The binary directory
      /home/ajitup/build/build_picongpu
    is already used to build a source directory.  It cannot be used to

build

    source directory
      /home/ajitup/code.PIConGPU/picongpu-master/src/picongpu
    Specify a unique binary directory name.

The CMakeLists.txt in /src/picongpu has the following line at no. 42

add_subdirectory("${CMAKE_SOURCE_DIR}/src/picongpu"
"${CMAKE_BINARY_DIR}/build_picongpu")


and it seems that the build directory is being called 3 times during
the whole project. It successfully builds the first time and when it
is accessed second or third time, it gives error.

I feel that -lpthread error could be linked to this error, as new
build directory does not get created. I tried changing gcc and glibc
versions but the error repeats.

What is your suggestion?

regards,
ajit
