[FFmpeg-user] cannot build shared libraries on Solaris

[Eric Thomas]

Hello,



My system administrator downloaded the FFmpeg 4.1 source code this week,
and I have been trying to build a set of shared libraries in Solaris. I
have successfully

built the static libraries.



Here is some system info:



uname –a

     SunOS devm 5.10 Generic_150400-61 sun4u sparc SUNW,Sun-Fire-V490



make –v

     GNU Make 3.81



gcc –v

     Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs

     Configured with:
/sfw10/builds/build/sfw10-patch/usr/src/cmd/gcc/gcc-3.4.3/configure
–prefix=/usr/sfw –with-as=/usr/ccs/bin/as –without-gnu-as
–with-ld=/usr/ccs/bin/ld –without-gnu-ld –enable-language=c,c++
--enable-shared

     Thread model: posix

     gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)



sed –version

    GNU sed 4.5





Configure cmd

     bash ./configure –prefix=/home/ffmpeg/FFmpeg-4.1 -–enable-shared



Here is the console output, after running ‘make’, then ‘make V=1
ffmpeg’, then ‘make V=1 ffmpeg’ again:

Can someone identify the problem?
