glibc-compat does not build on Pepper 39 #160

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install the pepper_39 NaCl SDK.
2. Set NACL_SDK_ROOT to the pepper_39 directory.
3. From naclports, run 'make glibc-compat'.

What is the expected output? What do you see instead?
Compile failure:
bin/naclports install glibc-compat

What version of the product are you using? On what operating system?
Pepper version: 39.
naclports version: 4eee512 (2014-11-09).
OS: Ubuntu 14.04.

Note: This library seems to be required by SDL, as of 33d366f (2014-10-15). 
Before that revision, SDL compiles successfully (but glib-compat still fails 
with the same error).

Does not fail against pepper_38 SDK.

I have no idea where include/fcntl.h comes from... it is in an out directory 
and I can't find its source code in naclports or anywhere in the Chromium / 
NaCl repositories.

I can't seem to reproduce this:

$ export NACL_SDK_ROOT=$HOME/nacl_sdk/pepper_39
$ ./make_all.sh clean
$ make glibc-compat V=1

Works fine for me at 4eee51203.

The file in question "include/fcntl.h" is found in source control at 
"ports/glibc-compat/include/sys/fcntl.h".  This file does not contain FIONBIO 
at 4eee512.  It looks like it was removed at e08c19df (on sept 11 2014) so I 
suspect you have a some kind of stale checkout?

BTW, I'm about to create branches for pepper_38, pepper_39 and pepper_40 in the 
naclports repo that we can use to avoid breaking older SDK as we make change 
(which are mostly tested against pepper_canary).

Running make with V=1 shows this additional line:

Prebuilt package was built with different SDK version: 38 vs 39

Running ./make_all.sh clean and then make fixes the problem.

So I guess there was some stale state around. It certainly wasn't a stale 
checkout of anything, but a stale build (which means the Makefile isn't smart 
enough about deciding what needs to be rebuilt).

I don't really understand how you could have got this error:

include/fcntl.h:11:1: error: "FIONBIO" redefined

Unless you have a file called ports/glibc-compat/include/fcntl.h.  Yes this file
was removed here:

https://codereview.chromium.org/418103005

If the fcntl.h was installed in the toolchain it would aprear as a full path 
name.

Sorry I don't have any other clues here.

Please re-open if it happens again.

Yeah I think what happened was I had ports/glibc-compat/include/fcntl.h left 
over from an old build (pre-pepper-38). Then when I re-ran make 
(post-pepper-39), it was not deleted and something was still referring to it.

Now it is working.
