[R-SIG-Mac] How to NOT remove build directory after building a package?

[Yoshihiko Baba]

Hi,


I have been trying to build a CRAN package from the source on Mac+Fink.  However, I got an error during the build process.  How can I tell R not to remove the temporary build directory?


checking for gsl-config... /sw/opt/gsl25/bin/gsl-config
checking if GSL version >= 2.1... checking for gcc... gcc
checking whether the C compiler works... no
configure: error: in /private/tmp/RtmpqJYplW/Rbuildc37f217e13c4/gsl': configure: error: C compiler cannot create executables See config.log' for more details
ERROR: configuration failed for package 'gsl'
removing '/private/tmp/RtmpqJYplW/Rinstc37f5c43ba09/gsl'
-----------------------------------
ERROR: package installation failed


I am using Fink because Fink can install multiple versions of libraries (gsl in this case).  However, to have multiple versions, GSL libraries are installed in non-standard direcotry (/sw/opt/gsl25).  By setting:
$ export GSL_CONFIG=/sw/opt/gsl25/bin/gsl-config
I have managed to tell the location of GSL, but gcc failed somehow.  But the config.log was deleted by R.


Thanks
