Read-only /usr/include??

Hello,

I am trying to install in QNX 6.1 a GTK 1.2.8 port that I downloaded
from your ftp: server, and used to work in last year’s version of QNX. I
have tried to copy a tree of files on /usr, but I just cannot modify
anything on certain subdiretories of /usr (/usr/include, /usr/bin). cp
says that it is a “Read-only filesystem”; it
is strange, because I can see “w” permissions everywhere, and such
things did not happen in the older version of QNX. Of course, I have
entered the system as root.

Which is the problem with modifying /usr/include? Is there a better
way to install GTK, anyway?

Best regards,

Hi Joaquin,

I believe if you have the BSP’s installed they mark the /usr area as
readonly. Try uninstalling the BSP’s (remove them, not just deactivate).

Also uninstall DDK’s.

Sorry, I do not understand which BSP you refer; perhaps something I have
installed
as a package? I will look and try.

It must be an unusual way to mark something as readonly, because write
permissions
seem to be enabled for the owner.

Will this be fixed in 6.1.1?

This is, I assume the same problem with the DDK’s marking /usr/help as read
only?

Well, I have turn to the Intaller, and I removed DDK ( I have not installed
any BSP). Now I can modify the /usr/* directories, without any problem, so I
was able to install gtk1.2.8, when I try to compile a program that uses gtk
the linker complains that…

libc.so.1 necessary for libgtk.so may conflict with libc.so.2

Anyway it seems to work fine. Can anyone explain this, so that I know how
much should I worry? Perhaps someone has ported gtk to the new version of
neutrino?

Best regards,


Joaquin

The port of gtk that you are using was linked againts the GNU libc c (6.0.x system).
Since libgtk is using so.1 c calls, and your app is going to use so.2 (dinkum) c
calls there is a slight possibility that there might be a conflict (mixup) between the
two. In theory this should work, but the best way would be to test your application.
