Compile error: cannot find libobjc.so.3

[nobicycle]

Hi,
I would love to get Oolite 1.77 working but:

Code: Select all

Compiling file src/Core/Universe.m ...
 Linking objc_program oolite ...
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/bin/ld:[b] cannot find libobjc.so.3
[/b]

My system is :

• x11-drivers/xf86-video-nouveau-1.0.7
  Linux tower 3.8.0-sabayon #1 SMP Fri May 24 17:20:54 UTC 2013 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ AuthenticAMD GNU/Linux

A search
find / -name " libobjc.so.3"
returned nothing.


The above happens when compiling using a Gentoo ebuild.

If I try the nightly build, oolite-trunk-1.77.1.5683-dev.linux-x86_64.run I get:

Code: Select all

sudo ./oolite-trunk-1.77.1.5683-dev.linux-x86_64.run

Sounds like a missing or misconfigured package. I'm not familiar with gentoo's packaging system, but there's a reference to gnustep-base/libobjc2 on the internet, so maybe there's a libobjc3 available as well in the same area?

If I try the nightly build, oolite-trunk-1.77.1.5683-dev.linux-x86_64.run I get:

Without libobjc installed it probably wouldn't actually run even if you could install it, but I would guess the cause is that you have /tmp mounted noexec - see this thread.

I posted this on the website of the distro (Sabayon) I use:

Oolite - Object Oriented Elite

Elite was an 80's space trading game, an excellent combination of strategy and shoot-em-up.
OOlite is an award winning more modern version, under active development. http://oolite.org/

Unfortunately I cannot get it to run.

It is not present in entropy and emerge produces the following:

Compiling file src/Core/Universe.m ...
Linking objc_program oolite ...
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find libobjc.so.3

libobjc is a dependency of the following:

Version 1.77 (latest) of oolite is in the "rion" overlay.
eix --deps libobjc

emerge gnustep-base/gnustep-make-2.6.4 produces

* The libobjc.so version used for gnustep-make has changed

* You must rebuild all gnustep packages installed.

When I follow these instructions, I get

* IMPORTANT: 7 news items need reading for repository 'gentoo'.
* Use eselect news to read news items.


These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds to satisfy "sys-devel/base-gcc:4.6".
* gnustep-updater is stopping here:
* Fix the problem and start gnustep-updater again.

So I am stuck at

there are no ebuilds to satisfy "sys-devel/base-gcc:4.6

Any ideas?

I don't know if this will help (I'm windows) but a quick google turned up this:

libobjc.so.x seems to come with the Objective-C frontend for gcc (often called gcc-objc ).

run

Code: Select all

gcc -v

, in the output look for --enable-languages= .

it should list objc as one of the languages present.

Hi nobicycle.

Did you have any chance with your issue or with this thread?
