[ERROR]: Lazarus32 BIG-IDE NOT Build
??????????????????????????????????????????????????????
/////////////////////////////////////////////////////////////////////////////
I am new to lazarus, I 'm wondering how long it is towards the success of building the bigIDE. (building win32 on 64bit win7 OS)
Can anyone help me out? thank you very much!

The problem is solved.
the cause of the problem is due to FPC2.60 I had installed before, So I removed it before compiling the big IDE.
I found it on the Lazarus forum, that a patch is done to the virtualtree package in order to build with FPC 2.70, which had been applied to CT 2.8 already (what a quick action! great CT developers.).

so please remove this thread!

Thanks Sir
CT use always the latest working SVN revisions
have fun
