Can't build symdiff from within devsim

[Noe Nieto]

Hi,

I'm trying to build devsim from scratch on Fedora 27, but the process fails when compiling symdif with "fatal error: Python.h: No such file or directory".

For example:

[nnieto@starblade devsim] $ pwd
/home/nnieto/DevSim/devsim
[nnieto@starblade devsim] $ git submodule init external/symdiff
[nnieto@starblade devsim] $ git submodule update external/symdiff
[nnieto@starblade devsim] $ cd external/symdiff/
[nnieto@starblade symdiff] $ scripts/setup_fedora_27.sh
 .... [Finish ok]
[nnieto@starblade symdiff] $ cd linux_x86_64_debug/
[nnieto@starblade linux_x86_64_debug] $ make -j2

The fedora build and scripts are just the same as the one on the git repos. The Devsym revision is 18109d226d8d8178fd15c4d7d9bdb766e027d559

Any idea what could be wrong?

Hi Noe,

I am able to build using a fedora 27 docker image with
devsim/scripts/build_fedora_27.sh

It installs all of the dependencies that should be required. Testing
it, I just found that "make" was missing, so it is now added. I also
made it now "make -j4".

Please do a git pull and run this script.

Regards,

Juan

Yessss it works now!

Thanks

[Noe Nieto]

I built DevSim on another laptop with Fedora 28. The script fails due to a wrong directory path. Besides that, it compiles cleanly.

I just sent a PR for the directory path fix.
