Hello all! I'm experiencing some difficulty getting a very simple Windows.Forms application (built on Windows) to run on Ubuntu Linux (5.10). When I look on the web, I see that others have had a similar problem. I've tried following the troubleshooting instructions posted at http://www.mono-project.com/DllNotFoundException, but have reached a dead end with my line of enquiry.
Before I describe the troubleshooting steps I've taken, I should give a little background. I installed Ubuntu Breezy, followed by Mono 1.1.8 taken from the distribution's "universe" repository on my Apple laptop. I encountered some problems with Windows.Forms applications, so I decided to install a more up-to-date version of Mono, again on Ubuntu Breezy, but this time on my desktop PC. Preferring to use Synaptic Package Manager to install the software, I found repository details at http://npw.net/2005/12/26/ubuntu-breezy-backports. With this version of Mono (1.1.13.1), I experience the same problem as raised in the recent "Mono hangs after looking up XKeycodeToKeysym" thread. At this point I obtained the "Linux installer for x86" from the Mono downloads page and installed Mono 1.1.13.2 into /opt/mono. Now to the troubleshooting session: $ MONO_LOG_LEVEL=debug mono HelloWorld-Win.exe <snip> Mono-INFO: DllImport attempting to load: 'gdiplus.dll'. Mono-INFO: DllImport loading location: 'libgdiplus.dll.so'. Mono-INFO: DllImport error loading library: 'libgdiplus.dll.so: cannot open shared object file: No such file or directory'.

(HelloWorld-Win.exe:16639): Mono-WARNING **: DllImport unable to load library 'libgdiplus.dll: cannot open shared object file: No such file or directory'. <snip> The troubleshooting instructions say that the directories specified by the $LD_LIBRARY_PATH environment variable will be searched. I elected to have the installer modify my ~/.bashrc file, so when I check my environment variables, I see: $ env | sort <snip> LD_LIBRARY_PATH=/opt/mono/mono-1.1.13.2/lib: <snip> Then, checking up on the dynamic linker, I get: $ ldconfig -p | grep libgdiplus libgdiplus.so.0 (libc6) => /usr/lib/libgdiplus.so.0 libgdiplus.so (libc6) => /usr/lib/libgdiplus.so Although the troubleshooting instructions describe a procedure for forcing the dynamic linker cache to be rebuilt, the implication is that rebuilding the cache is merely a more elegant way of fixing the problem than setting the $LD_LIBRARY_PATH variable. Since that environment variable has already been set by the installer, will there be any benefit from rebuilding the cache? Note that /opt/mono/mono-1.1.13.2/lib contains both libgdiplus.so and libtiff.so.3.5 (but not libtiff.so.3). Is it the missing libtiff.so.3 that's the real problem? I ran the installer using sudo so that it was able to create the mono directory within /opt. Would I have done better to accept the default install location, in my home directory? Thanks for reading this far. Any help would be greatly appreciated. --Andrew _______________________________________________ Mono-winforms-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-winforms-list
