Perhaps

It didn't. At least until now, neither package was required fortunatelly

Seems? Your feelings about it are also irrelevant. I'm going to assume that because you're trying to build libX11 that the end goal is to build xorg-server. Building libX11 by itself makes little sense, because the library is useless without the server itself. That said, building a functionally useful xorg-server requires most, if not all of what is shown in that list, except for maybe the Wayland stuff. Follow this link and look at the packages listed as required dependencies. Then follow the links to those dependencies and see that they too have dependencies. That's why I referred to X11 as a software stack. It is not just one or two packages to build before it is ready to use.

I did not mentioned my feelings, just mentioned a fact. My ultimate goal is not xorg-server, only a couple libraries of it.

Anyway I was able to build X11. However, trying to compile libRes I am receiving it:

That is why I told you to use the latest versions. There have been lots of changes since the versions you chose to download. If you start by grabbing all the latest versions you'll side step a huge number of potential issues, including packages that may not compile at all in 2019.

Well, seems to be better. Unfortunately this time I am using them and this problem still appeared. I am using the blfs link: http://www.linuxfromscratch.org/blfs...d/x/x7lib.html. There it mentions xcb 1.13.1 that is the version I am using and the Xext version I am trying to biuld is also the same 1.3.3.

It is complaining

but this time the file it is present at

Code:

X11-1.6.7/include/X11/Xlibint.h

So I do not know why he is not finding it.

This is why I asked if you've tried to build software before. Are you using the same --prefix= for both packages?

Sorry I was confused. The problem arises when trying to compile libXExt (that I will need to compile libXres). The configure command is

Code:

./configure --prefix=/media/34GB/Arquivos-de-Programas-Linux/Xext-1.3.3/ PKG_CONFIG_PATH=/media/34GB/Arquivos-de-Programas-Linux/Xorgproto-2018.1/share/pkgconfig/:/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/lib/pkgconfig/:/media/34GB/Arquivos-de-Programas-Linux/Xcb-1.13/lib/pkgconfig/:/media/34GB/Arquivos-de-Programas-Linux/Pthread-stubs-0.1/lib/pkgconfig/:/media/34GB/Arquivos-de-Programas-Linux/Xau-1.0.9/lib/pkgconfig/

I also tried to add a

Code:

export CPPFLAGS=-I"/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/include/"

and a

Code:

export LDFLAGS=-L"/media/34GB/Arquivos-de-Programas-Linux/X11-1.6.7/lib/"

but it did not changed the outcome

as far as I know -L<dir> is not required for CPP. From the other hand export CPPFLAGS="anything" will overwrite the content of CPPFLAGS (the previous settings will be lost).
FPE stands for Floating Point Exception.

My mistake, I meant LDFLAGS, not CPPFLAGS.

Well, I guess I typed something wrong. Tried again with these flags and now worked.

*******EDITED2********

No, I probably did not type anything wrong. Problem happens if I export CPPFLAGS and LDFLAGS after a compilation that went wrong. Setting both variables before trying the compilation worked. I wonder what is the difference.............
