#32 Can't compile kscope 1.9.0 on kubuntu 8.10.

[ghostkadost]

I have installed the necessary dependencies(qscintilla2, lib-qt4-dev (4.4.3)) etc. Installed gcc version is
g++ (Ubuntu 4.3.2-1ubuntu11) 4.3.2

On compilation these are the error messages that I get

[Elad Lahav]

It looks as though the linker is failing to find libkscope_core.so. Can you please do a 'make distclean' and start over, posting the entire output of the build process? I'd like to see if libkscope_core.so is being built, and if the linker for libkscope_cscope.so is using the correct flags.

Output log of make

[ghostkadost]

I have uploaded the output of make. It indeed is not able to find libkscope_core.so at linking stage. Further there is a similar problem while linking in the app directory.

[Elad Lahav]

The linker in your setup includes the --no-undefined flag, which prevents libkscope_cscope.so from linking without a reference to libkscope_core.so.
To solve the problem, add the following line to cscope/cscope.pro:

LIB=-L../core -lkscope_core

Run qmake and make again. I will fix the problem in the next release.

Version 1.9.2 on Ubuntu 8.10 does not compile with the common settings in .pro files (Qsci include in invalid, because it is in qt4 subdirectory).
