>From http://bugs.r-project.org/cgi-bin/R:
If you are not sure whether you have observed a bug or not, it is a good
idea to ask on the mailing list R-Help by sending an e-mail to
[EMAIL PROTECTED] rather than submitting a bug report.
I'm wondering whether to submit a bug report on this:
==============================================================
> install.packages("nlme")
((several lines removed))
* Installing *source* package 'nlme' ...
** libs
i686-pc-linux-gnu-gcc -I/usr/lib/R/include -I/usr/lib/R/include
-I/usr/local/include -fvisibility=hidden -fPIC -O2 -mcpu=i686 -pipe
-std=gnu99 -c corStruct.c -o corStruct.o
cc1: error: unrecognized option `-fvisibility=hidden'
make: *** [corStruct.o] Error 1
ERROR: compilation failed for package 'nlme'
==============================================================
Here's my configuration:
> uname -a
> Linux conception.wustl.edu 2.6.12-gentoo-r9 #3 SMP Mon Aug 29 14:00:05
> CDT 2005 i686 Intel(R) Pentium(R) 4 CPU 2.80GHz GenuineIntel GNU/Linux
This error occurred after I upgraded my gcc to the newest version (it
also occurred with the previous version):
> gcc-config -c
> i686-pc-linux-gnu-4.2.3
To see if the "-fvisibility=hidden" problem was a bug in gcc, I tried
using it in a toy compilation:
> echo 'main() { }' > in.c
> gcc -fvisibility=hidden in.c
This returned without an error.
Then I tried:
> i686-pc-linux-gnu-gcc -I/usr/lib/R/include -I/usr/lib/R/include
-I/usr/local/include -fvisibility=hidden -fPIC -O2 -mcpu=i686 -pipe
-std=gnu99 -c in.c
> `-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.
> in.c:1: warning: return type defaults to 'int'
Conclusion: my gcc seems to accept -fvisibility=hidden.
So: Should I submit a bug report on this? Thanks -
