lazarus compiles but doesn't start

[andi456]

Hi everybody,
to make the cvs sources compile, I needed to comment out two lines corresponding to the following error:

Code: [Select]

grids.pas(7494,19) Error: Unknown record field identifier "WPARAMLO"
grids.pas(7877) Fatal: There were 1 errors compiling module, stopping
grids.pas(61,12) Error: Compilation aborted


But starting lazarus gives this result:

 

Code: [Select]

This is the gdb backtrace corresponding to the above:

The problem appears under gentoo linux amd64.


Thanks in advance.

Current Lazarus CVS needs FPC 2.0.0 Did you install that as well?

Oops, just noticed you are using 64 bit Linux so maybe there is something else wrong.

[andi456]

Well, I got fpc-2.0.0 and sources installed, that cannot be the problem, there must be something else. With the latest cvs-update the result remains the same, whereas the backtrace is slightly different:
