How To Use Different Enet Path

[baDibere]

Hi there,

My distribution has only Enet 1.3

So I compiled Enet 1.2 and placed it to /opt/enet12

Before compiling 0AD, I changed source/lib/external_libs/enet.h:30 like #include "/opt/enet12/include/enet/enet.h"

So there is no compilation error about enet and 0ad. But

ldd pyrogenesis

says that pyrogenesis needs /usr/lib/libenet.so.1. So, this is a Enet 1.3 library.

What should I do to use /opt/enet12/lib/libenet.so.1 instead of /usr/lib/libenet.so.1

Regards.

(What distro is this? I thought most still had 1.2, or had it under a name "enet-old" or similar.)

If you have the library in a non-standard location, I think the only way to make it work is to edit build/premake/extern_libs.lua, around line 115 where it says tinsert(package.links, "enet"), and add a new line like

tinsert(package.libpaths, libraries_dir.."/opt/enet12/lib")

then run update-workspaces.sh and make again. I think that should take precedence over /usr/lib and make it compile with the right version. I'm not sure whether it'll still use the old when running, though - in that case you might have to run it like 'LD_LIBRARY_PATH=/opt/enet12/lib ./pyrogenesis' to make it look in the right place.

(It would be nice if we had a better way to handle this situation, but I don't know what would work )

I use Pardus GNU/Linux and I prepare an unofficial PiSi(*) repository for Pardus.

Unfortunately enet-old or similar one is not available for Pardus and I prepared enet12 package. Since other applications may use Enet 1.3, I want to keep it and I installed Enet 1.2 to a non-standart directory (/opt/enet12)

Your solution works. But instead of

tinsert(package.libpaths, libraries_dir.."/opt/enet12/lib")

,

I used

tinsert(package.libpaths, "/opt/enet12/lib")

Because, if I use previous one, something like "-L"../../../libraries//opt/enet12/lib"" is added to pyrogenesis.make. Since I changed, only "-L"/opt/enet12/lib"" is added and I think the right one is that.

After compiling, "ldd pyrogenesis" says that

libenet.so.0 => not found

So I used

LD_LIBRARY_PATH=/opt/enet12/lib ./pyrogenesis

and it works.

(*) PiSi is Pardus's package management system.
