Subject: [Rd] Cross-compile errors under R-2.4.0 and R-2.4.1
Message-ID: <f13f1c9c0701190046n4c487253l2925427712155002@mail.gmail.com>

Dear all,

I already posted a question regarding this to an existing thread:
http://tolstoy.newcastle.edu.au/R/e2/devel/06/10/0852.html#start

I apologize for the double posting but I have some further information
that might be illuminating.

I am trying to cross-compile my R-package under ubuntu linux, kernel
2.6.17-10-generic, on an IBM T60.

I am following the suggested steps in
http://cran.r-project.org/doc/contrib/cross-build.pdf

I have tried changing R = R-x.x.x (2.3.1, 2.4.0 and 2.4.1) in
http://cran.ii.uib.no/doc/contrib/Makefile-rcb

1) For R-2.3.1 everything works fine
2) For R-2.4.0 I receive the following error messages from 'make R':

../extra/pcre/libpcre.a(pcre_dfa_exec.o):pcre_dfa_exec.c:(.text+0x1f2a):
more undefined references to `__pcre_ucp_findprop' follow
collect2: ld returned 1 exit status
make[4]: *** [R.dll] Error 1
make[3]: *** [../../bin/R.dll] Error 2
make[2]: *** [rbuild] Error 2
make[1]: *** [all] Error 2
make[1]: Leaving directory

There is already a post that seems to address the same error:
http://tolstoy.newcastle.edu.au/R/e2/devel/06/10/0852.html#start

However, I have tried the suggestions there with no further success
and I am awaiting further instructions before pursuing that solution.

3) For R-2.4.1 I receive the following error message from 'make R',
under 'Making package tools':

preparing package tools for lazy loading
Error in makeLazyLoadDB(ns, dbbase) : could not find function "seq_along"
Execution halted


Hope this is illuminating and that the 'bugs', whether it is in R or
in PCRE, can be resolved for the next release, this would be highly
appreciated. Meanwhile, any suggestions as to how I can cross-compile
successfully under R-2.4.1 are most welcome.

Best wishes,
Daniel Berg
