I am trying to build code under OpenWRT. I find that the uClibc compilation breaks [fails to build saying linux/errno.h is not found] if I have an environment variable [defined as export dst=/projects//... on a network-share].

If I change the name of that environment variable [to pkdst] - I do not see that error and OpenWRT build succeeds.

Is $dst some kind of "special" shell-variable under BASH?

  • Thanks Marc. I should have mentioned in my post that I had already looked at that page. I also looked on google and in the BASH documentation on my system and online. It appears that $dst might be used "internally" by OpenWRT during compile --- since it breaks the toolchain compile of uClibc. This is what I am trying to confirm. – pkal Jul 28 '15 at 13:59
