Problem with compilation under Debian Testing about devsim

[tcaduser]

It looks like it needs to be added here:
/src/main/CMakeLists.txt

On the TARGET_LINK_LIBRARIES line for 'devsim_py', add ${PTHREAD_LIB} to the very end of the line before the end parenthesis.

Please let me know if it works. Please build using:
make VERBOSE=1

for additional debugging information.

Hello,

Thanks for that suggestion. That solved the problem with pthread. However, there is a complaint w.r.t libdl. What do I add for this?

Thanks a lot,

Which setup script are you using? This may affect which .cmake file to change below.

There may be 3 solutions to this problem.

1. Add "-ldl" to the end of the link line for "devsim_py" after PTHREAD_LIB

in src/main/CMakeLists.txt

or

1. SET(SQLITE3_ARCHIVE -lsqlite3)

in ubuntu_12.04.cmake.

or

1. SET(SQLITE3_ARCHIVE -lsqlite3 -ldl)

in ubuntu_12.04.cmake.

[tcaduser]

For reference, it looks like Debian might be using features in sqlite3 that were not be used in previous versions of ubuntu.

http://www.sqlite.org/howtocompile.html

shows what options require the use of "-ldl" and "-lpthread".

Thanks again! I added -ldl to the link line for devsim.py. I also had to make the following change
BLAS_ARCHIVE /usr/lib/atlas-base/atlas/liblapack.a /usr/lib/atlas-base/atlas/libblas.a /usr/lib/gcc/x86_64-linux-gnu/4.7/libgfortran.a
in ubuntu_12.04.cmake, since I dont have the acml libs loaded on my machine. With these changes, I am able to successfully compile the code.

Your approach to writing a TCAD tool looks very interesting! I am eager to play with the examples.

Regards
Arvind

Thanks for trying the software. Your blas and lapack should work, except some of the regression tests will fail due to slight numerical differences.

I will update the build scripts soon so '-libdl' and '-lpthread' are added.

Please let me know if you have any questions about using the software.

dl, pthread issues should be fixed with new Ubuntu 14.04 scripts in commit 83028f8
