SVD_MathPlugin error

Hi all

I just compiled indilib and the eqmod driver on a RPi 3B+.
When starting ` indiserver indi_eqmod_telescope`, I get this error.
Driver indi_eqmod_telescope: EnumeratePlugins - cannot load plugin /libindi_SVD_MathPlugin.so error /libindi_SVD_MathPlugin.so: cannot open shared object file: No such file or directory
I'm sure it's looking in the wrong place, because the fs-root is an unlikely place to find it :)
By linking the actual file to the fs-root it works fine.

Hi Niko,

the problem is here:
--- a/libindi/libs/indibase/alignment/MathPluginManagement.cpp
+++ b/libindi/libs/indibase/alignment/MathPluginManagement.cpp
@@ -361,7 +361,7 @@ void MathPluginManagement::EnumeratePlugins()
     #endif
 
     dp    = opendir(MATH_PLUGINS_DIRECTORY);
-    snprintf(MATH_PLUGINS_DIRECTORY, 2048 - 1, "%s%s", MATH_PLUGINS_DIRECTORY, "/");
+    snprintf(MATH_PLUGINS_DIRECTORY, 2048 - 1, "%s%s", INDI_MATH_PLUGINS_DIRECTORY, "/");
     if (dp)

I send a PR to Jasem Fix issue: cannot load plugin /libindi_SVD_MathPlugin.so
which fixes the problem:

Thanks for fixing this in record time.
I wish I could be more of help and fix stuff myself rather than just reporting errors.

Hi, I'm still getting this error. I'm running Ubuntu Mate 16.04 on a Raspberry Pi 2. INDI was installed from the ppa.

Thanks,
David.

Hi David,
I have the same problem but solved it temporary until new version is out..
I did a softlink like this :
sudo ln -s /usr/lib/arm-linux-gnueabihf/indi/MathPlugins/libindi_SVD_MathPlugin.so /libindi_SVD_MathPlugin.so
If you have another distro the path could be different, I'm using Ubuntu-mate on a RPi.
