Hi,

I try to install Python interface and I have the following problem.

Seems that one file is missing ...

Code: Select all

python setup.py install

Thanks for your help !!

I think you have to specify where to find the header? Because I think this one was just the first. The compiler is not finding any I guess...

try:

Code: Select all

python setup.py build_ext -I/opt/openEMS/include -L/opt/openEMS/lib -R/opt/openEMS/lib"
pyhton setup.py install

Where "/opt/openEMS" is obviously where you installed openEMS by the usual means...

I assume the installed version of openEMS is the latest version from master branch as well? Not the last released version?

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

Most of the time these are dependency-issues. You need to install a package called python-dev. This package includes header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications. When encountering this error please note before the error it may say you are missing a package or header file — you should find those and install them and verify if it works

For Python 2.x use:

Code: Select all

$ sudo apt-get install python-dev

If you using python3, try to replace python-dev with python3-dev

For a specific version of Python 3, replace x with the minor version in

Code: Select all

$ sudo apt-get install python3.x-dev

I have the same problem, both with the v0.0.35 released version as of with the latest git version. Unfortunately i have no experience with the cython build environment. So any help is appreciated.

One observation is that the CSXCAD folder in the build directory is empty.

The missing file do exists in the /opt/include/CSXCAD directory.

Here the setup output:

Code: Select all

python3-dev is installed

[thorsten]

Well the command looks fine to me. I assume the file "/opt/include/CSXCAD/ParameterObjects.h" is indeed available?

[cnkz]

Yes, the file "ParameterObjects.h" is in the include folder given by the -I flag to the compiler, but the compiler seems not to use the folder given by -I. (i tried different install targets not only /opt but also $HOME/opt/openems to avoid access problems)
