Error whilst compiling XOrg [solved]

[ianw1974]

I downloaded the single source .tag.gz from one of the mirrors and am currently compiling XOrg. I know I could use an RPM to do this, but I wanted to learn along the way.

 

However, I'm getting a problem. This is what I've done so far:

 

Pre:

 

Made sure that I had installed gcc, make, bison, flex, zlib, ncurses, fontconfig, expat and Perl. The only thing I couldn't check was C library development package, am assuming it's installed, because I don't know what the RPM is called for it.

 

1. Create a directory called "build".

2. Ran "lndir ../xc" to create a shadow link to "build".

3. As I use bash (Bourne), I typed the following: make World > World.log 2>&1

 

It's now bombed out with the following error messages:

Can someone tell me what I seem to be missing, so that I can carry on with the build?

 

Much appreciated!!!

png.h is missing? try searching for libpng or libpng-devel. you might need those to get the required header files.

 

note that i am only guessing here and i dont have the luxury of googling to verify. :(

 

ciao!

[ianw1974]

Cool, just done that so re-running now to see what happens!

 

Will keep you posted in case any more pop up!!

 

Thanks v much!

[ianw1974]

Well, it seems to have compiled and installed OK so far.

 

I guess it must all be OK!!!!! :P

[ianw1974]

Huge huge problem now!!!

 

I decided to go into the MCC gui, and changed it so XOrg runs automatically. Now I've done this, the mdkkdm screen will not let me type in it or anything.

 

Sounds like the xorg has got screwed somewhere. Before this however, I was loggin on getting to the CLI prompt and then typing startx and all was fine.

 

I can run failsafe, but I don't know how to turn off the run XOrg automatically option. What's gone wrong to stop me logging on the GUI?

[ianw1974]

It's OK now. I solved it :D

 

Booted failsafe, did the following:

 

service network start

 

urpmi the source for thacs rpms, and then installed Xorg over the top of what seems to be my partially failed compilation.

 

When I rebooted normally, I could get in fine. Seems something went amiss somewhere, don't know what, but I'm back to normal!

 

And no rebuild either, cool :P
