Hello,
I know it has been reported by Tobias on lfs-support, but it seems to me
it is an issue with the current version of check, and it should be
addressed in the book:
- the error occurs during make:
----------------------------
/bin/bash ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I.
-I.. -O3 -pipe -march=native -Wall -ansi -pedantic -Wextra
-Wstrict-prototypes -Wmissing-prototypes -Wwrite-strings
-Wno-variadic-macros -MT putenv.lo -MD -MP -MF .deps/putenv.Tpo -c -o
putenv.lo putenv.c
libtool: compile: gcc -DHAVE_CONFIG_H -I. -I.. -O3 -pipe -march=native
-Wall -ansi -pedantic -Wextra -Wstrict-prototypes -Wmissing-prototypes
-Wwrite-strings -Wno-variadic-macros -MT putenv.lo -MD -MP -MF
.deps/putenv.Tpo -c putenv.c -fPIC -DPIC -o .libs/putenv.o
putenv.c:5:1: error: expected identifier or '(' before '{' token
make[2]: *** [putenv.lo] Error 1
make[2]: Leaving directory `/mnt/lfs/sources/check-0.9.9/lib'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/mnt/lfs/sources/check-0.9.9'
make: *** [all] Error 2
------------------------------
The reason is clearly a syntax error in the file putenv.c :
----------------------
> less lib/putenv.c
#include "libcompat.h"
int
putenv (const char *string CK_ATTRIBUTE_UNUSED);
{
assert (0);
return 0;
}
-------------------------
On the other hand, this file should not be compiled, since it is a
fallback if putenv is not present, but it is easy to check that putenv
is in the glibc library. Now, in configure output, we have:
--------------------------
checking for pipe... no
checking for putenv... no
checking for setenv... no
checking for sleep... no
checking for strdup... no
checking for strsignal... no
checking for unsetenv... no
--------------------------------
and config.log has:
-----------------------------
configure:13124: checking for putenv
configure:13124: gcc -o conftest -O3 -pipe -march=native -Wall -ansi
-pedantic -Wextra -Wstrict-prototypes -Wmissing-prototypes
-Wwrite-strings -Wno-variadic-macros conftest.c -lrt >&5
conftest.c:71:1: warning: function declaration isn't a prototype
[-Wstrict-prototypes]
conftest.c:80:1: warning: function declaration isn't a prototype
[-Wstrict-prototypes]
/mnt/lfs/tools/bin/../lib/gcc/x86_64-unknown-linux-gnu/4.7.2/../../../../lib64/librt.so:
undefined reference to `__pthread_get_minstack@GLIBC_PRIVATE'
collect2: error: ld returned 1 exit status
configure:13124: $? = 1
---------------------------------
in fact, -lrt should not be used without -lpthread. Now, the reason I
think is that configure has LIBS=-lrt too early, that is before testing
the thread library. It is a bug, which I plan to report upstream.
A workaround for now is to change the configure command:
LDFLAGS=-lpthread ./configure --prefix=/tools
I am amazed that nobody else has reported that: I use jhalfs on Debian
sid (64 bit).
Regards
Pierre
