custer installation issue (again)

Hi guys,

I am going through the same installation issue again....

A year ago, with your help I have installed ngsolve in a cluster... but I have no access to the cluster anymore....

Now, I would like to get ngsolve installed on my local cluster, but it cause issue again as usual.

So, after make install, I got the following error message at the final linking stage (100%):

/users/gfu1/data/ngbuild/ngsolve-install/lib/libmesh.so: undefined reference to `gzclose'
/users/gfu1/data/ngbuild/ngsolve-install/lib/libmesh.so: undefined reference to `gzwrite'
/users/gfu1/data/ngbuild/ngsolve-install/lib/libmesh.so: undefined reference to `gzopen'
/users/gfu1/data/ngbuild/ngsolve-install/lib/libmesh.so: undefined reference to `gzread'

A similar linking issue was found a year ago, but the fix there was simple...here I don't have a clue what's going on

Best,

Hi,

sounds like you are missing "zlib".
On my ubuntu 18.04 the package "zlib1g-dev" contains what you need. But at least for ubuntu, I thinks that's installed by default. Which OS are you using?

Best,

interesting....
I do have a zlib(what is there!?) issue initially, so, I passed the flags in cmake to the correct location
DZLIB_xxx=...
to locate zlib

I thought this shall be enough

We have a RedHat7 system...

Hi,

you could check your netgen cmake cache. This file is located in the netgen subfolder of you ngsolve build folder.
My CMakeCache.txt contains these lines. Which variable did you set? The location of the following variable should be used as hint to search for the header and the library.
Best,
Christoph

I have

ZLIB_INCLUDE_DIR:PATH=/gpfs/runtime/opt/zlib/1.2.8
//No help, variable specified on the command line.
ZLIB_LIBRARY:UNINITIALIZED=/gpfs/runtime/opt/zlib/1.2.8/lib

But I don't have
ZLIB_LIBRARY_DEBUG
or
ZLIB_LIBRARY_RELEASE
