Bug on Grads after update v18.12

[meteo60]

Hi,
I updated my UEMS from 18.8 to 18.12, since I have some bugs on grads (which is on 2.2.0 version vs 2.1 before update):
It's impossible to open grads:

Code: Select all

grads: error while loading shared libraries: libssl.so.10: cannot open shared object file: No such file or directory

So I made symbolic link:

Code: Select all

ln -s /usr/lib/x86_64-linux-gnu/libssl.so.1.0.2 /usr/lib/libssl.so.10
ln -s /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.2 /usr/lib/libcrypto.so.10

But new error:

Code: Select all

GX Package Error: dlopen failed to get a handle on gxprint plug-in named "Cairo" 
   libpng15.so.15: cannot open shared object file: No such file or directory

This user had the same error but he don't use grads in UEMS: http://gradsusr.org/pipermail/gradsusr/ ... 41576.html

I tried to put libpng15.so.15 in grads/lib directory, I can open grads but printim or gxprint is impossible:

Code: Select all

libpng warning: Image width exceeds user limit in IHDR
libpng warning: Image height exceeds user limit in IHDR
gd-png:  fatal libpng error: Invalid IHDR data

How I "solved" my problem? I made apt-get install grads, then I renamed grads/bin/grads to grads/bin/oldgrads and I made a symbolic link in this directory to open /usr/bin/grads. That's ok but I have grads 2.1 instead 2.2...

Any idea to use grads 2.2 in new UEMS?

I forgot to write the result of ldd command:

Code: Select all

ldd grads

I use opengrads 2.1 appositively and I find myself very well

Robert answered me:

The problem is that my path was left in the grads/lib/*.la (or ls/*la) file. You can edit the file to reflect your path or just remove
the grads directory and replace it with v2.1 from the previous release.

But there is another bug after, my answer:
I tested what you advised me, grads opens but immediately it closes with a "segmentation fault".
I export LD_LIBRARY_PATH to the good path before open.
Here the last lines of the result with strace -f grads -b command:

Code: Select all

For the moment I keep grads installed by apt-get... I keep too the last grads v2.1.a3 from previous version.

Here is Robert's answer, I think these issues will be fixed at the next update:

You are opening the wrong libraries. For the time being just use grads 2.1 from the previous release.

One thing I noticed in $UEMS/util/grads/grads/data/udpt, the directories were pointing to /usr1/UEMS/Development/UEMS/uems/util/grads/lib/libXXXX.so

I changed it to $UEMS/util/grads/lib/libXXXX.so and it worked.

I changed too but I have this error:

I also changed the path $UEMS/util/grads/grads/data/udpt, and it worked. Thanks hinsberj

Hi all, i resolved taking off the UEMS grads, i commented the section named: "# Set the GrADS environment variables" from $UEMS/etc/EMS.profile and in "PATH" definition i cuted the part: ":${EMS_UTIL}/grads/bin", later i was installed manually grads with the command: sudo apt install grads and that worked for me.

I noticed from Robert to switch from Linux Mint/Ubuntu/etc... to CentOS 7 and works for me.
