cross compiling problems

[madeupname]

I am trying to cross compile an embedded version of Konqueror to a blackfin processor. I have already done this using a SuSE configured host machine. Granted I am using a slightly newer version of software for the uClinux and cross compiling toolchain, but I fear this particular issue may be related to my Ubuntu host machine. I am very new to the Ubuntu distribution, this is my first exposure.

Does anyone have any clue as to why I might be seeing this error and/or how the best way for me to figure out the solutuion?

Actually in retrospect the "error" is probably a porting issue. I don't think my patch was installed quite right. However the "warning":

/usr/include/asm/errno.h:9:4: warning: #warning This machine appears to be neither x86_64 nor i386.

I fear is related to my Ubuntu distribution. So if anyone can enlighten me as to why I might be seeing this warning I would appreciate it.

I continue to struggle with various issues using Ubuntu that I haven't seen elsewhere.

I understand now what is going on. I corrected the code for a proper port to uClinux and the pthread_exit error disappeared. The other problem (within socket.h),persists and that also will throw a fatal error. The problem occurs because the cross compiler is picking up the Ubuntu system level /usr/include/asm/socket.h when it should be picking up the uClinux-kernel/include/asm-blackfin/socket.h. On my other host machine apparently the same thing occured but that was a SuSE box on a 32-bit machine and the system level socket.h was close to the embedded linux version.... close enough to compile. However my Ubuntu box is 64-bit and there is nothing but a stub at the system level /asm/socket.h hence a catastrophic failure....

Now that I understand it, I still am not overly clear on how to fix it. However, understanding the problem is half the battle right?
