Hello.. I want to compile a Linux app on my OpenBSD system.
The app. is called "Rainbow Crack" Password cracking tool. I found a site which has a .diff file and makfile.openbsd for download.
"rainbowcrack-1.2-openbsd-diffs" When I try to "patch -p0" or "patch -p1" it doesn't work. Anyone have anything that might work for what I want to accomplish? I am by no means a compile expert either. Any help is appreciated, thanks!

how do you try to compile the sources ?? gcc ?

build the source in linux:
make -f makefile.linux

i don't see where is your problem, install gcc and compile. I think that it will work.

It's OpenBSD I am trying to compile in, not Linux.. The app is meant for Linux, btu I have an openbsd patch.. (trying to build the app from source)

Here is what the output says after trying the "patch -p0 file.diff" cmd....

"
$ make -f makefile.openbsd
g++ Public.cpp ChainWalkContext.cpp HashAlgorithm.cpp HashRoutine.cpp RainbowTableGenerate.cpp -lcrypto -O3 -o rtgen
Public.cpp:16: sys/sysinfo.h: No such file or directory
*** Error code 1

Stop in /home/user/rainbowcrack-1.2-src/src (line 5 of makefile.openbsd).

Almost any Linux app taht uses the sysinfo header file will not work right on a BSD machine. Sometimes if you compile it on a linux system, it can run in linux compatability mode (if ur system is setup to support it) Check out our irc server[ irc.governmentsecurity.org ]. There is a channel dedicated to rainbow tables and there is at least one person i know of that succcessfully runs rcrack on a bsd system.

Ah.. ok thanks for info..
