Hello,<br /><br />I'm trying to build mdb tools (mdb_stat and mdb_copy inside libraries/liblmdb directory) on a Solaris 10 SPARC operating system with OpenLDAP 2.4.39. <br /><br />Is there some requirements for building the tools on this OS because i have a error during build ? <br /><br />Here is my result (while i do not set any specific gcc flags) :<br /># make<br />...<br />gcc -pthreads -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast   mdb_stat.o liblmdb.a  -o mdb_stat<br />Undefined                       first referenced<br /> symbol                             in file<br />fdatasync                           liblmdb.a(mdb.o)<br />ld: fatal: Symbol referencing errors. No output written to mdb_stat<br />collect2: ld returned 1 exit status<br />*** Error code 1<br />make: Fatal error: Command failed for target `mdb_stat'<br />#<br /><br />Notice that i use a gcc 3.4.3 and gcc option &quot;-pthread&quot; do not exist for this gcc release, i had to replace it by &quot;-pthreads&quot;. I try to read mdb.c for any specific options but i don't find anything...<br /><br />Notice also that i succeed to build OpenLDAP 2.4.39 with my Solaris 10 environment.<br /><br />Thanks,<br />--<br signature="separator" /><p style="margin-top: 0pt; font-size: 10pt; margin-bottom: 0pt; color: rgb(0, 0, 0); font-family: Arial,sans-serif;"><b>Frederic Poisson</b></p><div><br /></div><div><br /></div>
