Yes, it is possible, but we don´t have pre-compiled packages for Sparc.
Please install Free Pascal and then use it to compile Lazarus source code.
Compiling lazarus is as easy as: make clean all
On Free Pascal website I see that only Free Pascal 2.0.0 is available for Sparc/Linux:
http://www.freepascal.org/download.htmlSince the latest lazarus requires FPC >= 2.0.2 to compile you have some options:
* Use FPC 2.0.0 to compile FPC 2.0.2 source code on your computer and then use it to compile Lazarus 0.9.16
* Ask for a kind soul to create a fpc 2.0.2 release for sparc/linux for you.
* Use FPC 2.0.0 to compile a older lazarus, like 0.9.12 perhaps.
Also notice that FPC 2.0.4 is about to be released and in the spirit of open source, you may want to consider creating a binary version of FPC 2.0.4 for Sparc/Linux, so the install process of it and Lazarus will be easier for others after you. It should be easy, just compile the compiler, and package the result. If you need help doing this, please ask on free pascal mailling list.
I hope the instructions aren´t too long. Don´t hesitate to ask for more help!
