Hi:

I followed the steps in http://dlang.org/dmd-linux.html, but when I build a simple hello world program with:

rdmd hello.d

I get the following error:

rdmd hello.d
/usr/bin/ld: cannot find -l:libphobos2.a

I have copied dmd2/linux/lib64/libphobos2.a to /usr/lib64, but ld still can't find it.

Now I really wish all our servers are using ubuntu server..

Could anybody shed some light on where the problem is? I don't have much experience in linux except using apt-get in ubuntu.

Thanks.

Puming.

Did you install binaries or build the compiler from source?

$ rdmd -L-L/usr/lib64 a.d

You can permanently add this to dmd command-line by creating "dmd.conf" file: <http://dlang.org/dmd-linux.html#dmd_conf>

On Debian based systems, like Ubuntu, you can use "d-apt" repository: <http://d-apt.sourceforge.net/>

I used the dmd.2.064.2.zip, because when I install the rpm binary, it says there are dependency issues.

still get the same error.

I was using the default dmd.conf in the .zip package

Yes, I was using that at home.

Is "libphobos2.a" the same arch than the program you're building?

What architecture that CentOS box is, and give us your /etc/dmd.conf please.

Linux 2.6.18-308.el5 #1 SMP EST 2012 x86_64 x86_64 x86_64 GNU/Linux

I'm using the the dmd.conf in dmd.2.064.2.zip



[Environment]

#DFLAGS=-I%@P%/../../src/phobos -I%@P%/../../src/druntime/import -L-L%@P%/../lib64 -L-L%@P%/../lib32 -L--no-warn-search-mismatch -L--export-dynamic
DFLAGS=-I%@P%/../../src/phobos -I%@P%/../../src/druntime/import -L-L%@P%/../lib64 -L-L%@P%/../lib32 -L--export-dynamic

I commented out the -L--no-warn-search-mismatch because when building there's an error:

/usr/bin/ld: unrecognized option '--no-warn-search-mismatch'

same problem:

$DMDLOC/dmd2/linux/bin64/dmd hello.d
/usr/bin/ld: cannot find -l:libphobos2.a
collect2: ld returned 1 exit status
--- errorlevel 1


$ cat $DMDLOC/dmd2/linux/bin64/dmd.conf

[Environment]

DFLAGS=-I%@P%/../../src/phobos -I%@P%/../../src/druntime/import -L-L%@P%/../lib64 -L-L%@P%/../lib32 -L--export-dynamic

extracted src from dmd.2.064.2.zip and built phobos and dmd from there. fails even on setting LOAD_LIBRARY paths

$ export LD_LOAD_LIBRARY=$DMDLOC/dmd2/linux/lib64
$ export LOAD_LIBRARY=$DMDLOC/dmd2/linux/lib64
$ $DMDLOC/dmd2/linux/bin64/dmd hello.d
/usr/bin/ld: cannot find -l:libphobos2.a
collect2: ld returned 1 exit status
--- errorlevel 1

$ ls $DMDLOC/dmd2/linux/lib64
hello.o  libphobos2.a  libphobos2.so  libphobos2.so.0.	libphobos2.so.0..0  libphobos2.so.0..o

am i doing something silly here?

It's not dmd problem, it's up to ld linker and the issue is same for other compiled languages including C and C++. You should specify LD_LIBRARY_PATH variable in your system before executing any compiled D application. You can add export of this environment variable to your $HOME/.profile or $HOME/.bashrc depending on your system or edit paths in /etc/ld.so.conf.d or /etc/ld.so.conf. The other way is to copy libphobos to path where ld can find it by default, for example, /usr/local/lib.
