Unable to compile: Linux

Greetings,

I have been having difficulty with compiling following the provided instructions. Following the Build Source (Linux) instructions, I encounter the following:

Proceeding to the CMake instructions, I go to the nel source directory, create a build directory, and proceed as instructed:

So far so good. It's a headless machine that acts as a dedicated server, so it's unsurprising there's no XF86VidMode or XRandR

That's no good! I check, and iconv.h is in /usr/local/include. I clear things out and rerun CMake adding a -I/usr/local/include flag, then try again but get the same error. On a whim, I try without the -j3 flag and get a completely different error:

Any thoughts? I'll keep plugging away and post any solutions I find for any who come after me.
Thanks!

Hello,

look at line 213 on dynloadlib.cpp and change:

char *errormsg=dlerror();

into

const char *errormsg=dlerror();

and tell us if it works better

RE: Unable to compile: Linux - Added by xiphos almost 5 years ago

Thank you, that seems to have resolved that issue.
The other issue cropped up again, even with explicitely telling cmake to include /usr/local/include - or perhaps I am mis-understanding the syntax?

xiphos@metropolis:~/src/ryzom/code/nel/build> cmake -DWITH_TESTS=OFF -DWITH_TOOLS=OFF -DWITH_SAMPLES=OFF -DINCLUDE_DIRECTORIES=/usr/local/include ..

The fix was easy enough: edit all flags.make files to have -I/usr/local/include. There was also some weirdness going on with the AL libraries; even with the -I/usr/local/include flag it was failing. Yet if I ran the failing command exactly as it appeared with a make VERBOSE=1 manually, it concluded with out issues. This happened at a few locations, but I did not have the where-with-all to note which commands failed in this manner.

NeL has now compiled on FreeBSD AMD64. Since the FreeBSD ports tree is still on luabind 0.7, the Ryzom client/server is a different story, but I feel confident about tackling that one :)

Thanks again for the help! Hopefully this will come in useful for others, as well.
