Detailed instructions: ENG / RUS

Requirements:

• Lazarus RC2.2 (or trunk)
• FPC 3.2 (or trunk)

You can build ZCAD or ZCADELECTROTECH

Build ZCAD:

• make installpkgstolaz LP=/path/to/your/lazarus PCP=/path/to/your/lazarus/primary/config
• make clean
• make zcadenv
• make zcad LP=/path/to/your/lazarus PCP=/path/to/your/lazarus/primary/config

Build ZCADELECTROTECH:

• make installpkgstolaz LP=/path/to/your/lazarus PCP=/path/to/your/lazarus/primary/config
• make clean
• make zcadelectrotechenv
• make zcadelectrotech LP=/path/to/your/lazarus PCP=/path/to/your/lazarus/primary/config

make installpkgstolaz you need to do it only one time, this will install packages from 'cad_sources/components' and 'cad_sources/other' to your lazarus and will rebuild it
