I am using OpenSuse 10.2, I've installed fpc 2.0.4, the sources too.
When I try to install a
new component into Lazarus, then it compiles it with no problem, but
when trying to
build Lazarus, it creahes with the next error message (from link.res):

compiling.....

Compiling /usr/lib/lazarus/components/mpaslex/mpaslex.pp
Compiling codeexplorer.pas
Compiling codeexplopts.pas
Compiling buildfiledlg.pas
Compiling procedurelist.pas
Compiling extractprocdlg.pas
Compiling findrenameidentifier.pas
Compiling cleandirdlg.pas
Linking ../lazarus
/usr/bin/ld: cannot find -lpthread
lazarus.pp(119,1) Error: Error while linking

make[2]: Leaving directory `/usr/lib/lazarus/ide'
make[1]: *** [ide] Error 2
make[1]: Leaving directory `/usr/lib/lazarus/ide'

Please help to build Lazarus, it's vital to be albe to install
components!

Thanks for Your help!

Do you know what is lpthread? Do you find directory /usr/bin/ld on
your system?

Have you seen this thread?

I've read that thread, You're mentioning, but I don't think that this
is the
same problem. I've tried this with Lazarus 0.9.20 and 0.9.22, but I
have the
same problem. I've checked /usr/bin/ld linker is installed, I've
checked that
FreePascal contains a directory /usr/lib/fpc/2.0.4/units/i385-linux. I
think
that the problem migth be the letter S, because unit pthreadS exist,
but
unit pthread doesn't. I'm thinkig of a mispelling.

Please help, I can't use Lazarus if I can't build it!

Thanks!

This is on the FAQ:

I don't know which devel lib includes -lpthreads, but I think someone
else already had this problem before. Searching on the forum might
reveal a solution.

I would try either libpthreads-dev or libglib-dev (or -devel depending
on distribution)

I know about libraries on linux. As far as I know for ld the -lpthread
parameter means that it should search for the pthread library.
pthreadS library exist in
/usr/lib/fpc/2.0.4/units/i386-linux/pthreads directory. I think there
is a
mispelling in the script. Everywhere it referres to this library it
referres to as
pthreadS, with letter S at the end, but when I try to rebuild
Lazarus, it says /usr/bin/ld: cannot find -lpthread, so it calls that
library without letter S ![/u][/i]

I've resolved the problem. GLibc-devel and X11*-devel packages were
not
installed. Installing all these packages resolved the problem

Thanks For Your Help!
