Hi all,
I am using file-locking functions in C that can be found in the
<stdio.h> in Unix
extern void flockfile (FILE *__stream) __THROW;
extern int ftrylockfile (FILE *__stream) __THROW __wur;
extern void funlockfile (FILE *__stream) __THROW;
When submitting to CRAN I have troubles with the win-builder.
<stdio.h> in windows does not contain those functions. But I found them
in the <pthread_unistd.h>.
But even when including all possible header files for pthread like:*
*
*#include <windows.h>**#include <sys/locking.h>*
*#include <pthread_unistd.h>****#include <pthread.h>****#include <pthread_compat.h>****#include <pthread_signal.h>****#include <pthread_time.h>*
I am aways getting the same error from win-builder:
bed2vector.cpp:2667:19: error: 'flockfile' was not declared in this scope
flockfile(stream);
^
bed2vector.cpp:2670:46: error: 'getc_unlocked' was not declared in this scope
for (int ch = 0; (ch = getc_unlocked(stream)) != EOF;) {
^
bed2vector.cpp:2678:27: error: 'funlockfile' was not declared in this scope
funlockfile(stream);
^
bed2vector.cpp:2694:21: error: 'funlockfile' was not declared in this scope
funlockfile(stream);
^
So the header files are there, but the functions are not defined. I am
not an expert in C, but
have to submit a package that uses C-code. Does someone have more
experience with this?
Thanks,
Carmen

Ciao Mauro,
Posso disturbarti un secondo di pomeriggio e scendere un attimo? Ho un problema con C... cioe' io e linux no, ma Windows.
Sulle nostre macchine compila senza problemi ma su Windows mi da un errore.
Lancio il seguente commando:
g++ -m64 -std=gnu++11 -I"/lustre/home/clivi/programs/R-devel/include" -DNDEBUG -I"/lustre/home/clivi/programs/R-devel/library/Rcpp/include/" -I"/lustre/home/clivi/programs/R-devel/library/BH/include/" -I"/usr/lib/gcc/x86_64-redhat-linux/4.8.5/include" -I./ -D_FASTMAP -DMAQ_LONGREADS -lbz2 -O2 -Wall -mtune=core2 -c bed2vector.cpp -o bed2vector.o
Allegato il codice da eseguire.
