Hi Dave, I believe the build system will find the libm.a in rtems toolchain, which I used arm-rtems-5, There are a number of libm.a inside the toolchain, specific to soft / hard VFP features
here is the configure command line to build the rtems bsp: ../../rtems-master/configure --prefix=$RTEMS_ROOT/5 --target=arm-rtems5 --enable-rtemsbsp=tms570lc4357_launchxl --enable-posix --disable-networking --enable-rtems-debug --enable-maintainer-mode --enable-rdbg --enable-rtems-inlines --disable-multiprocessing --enable-cxx --enable-itron --disable-ada --disable-expada --disable-multilib --disable-docs TMS570_USE_HWINIT_STARTUP=1 ARM_TMS570LC4357=1 Remember that I have added LIBS = -lm inside my tms570lc4357.inc config file On Mon, Jul 25, 2022 at 10:05 PM DAVE ERICKSON <daveerick...@shaw.ca> wrote: > Hi Hongbo (Is that right?); > > > I have no experience with waf so I can't help there...over to joel... > > What I want to see is the output from the exact same shell (terminal, > BASH) that you are compiling with and may have environmental variables set, > is the computer's reply to you executing the > > which libm.* > > command. that will give you the list of libm.a, libm.so, libm.la files > that the bash shell / or c shell can find. > > It is important that it come from the identical shell because some of the > programs you are using may have set global scope environmental variables in > that shell that are trampling on other setup in makefiles variables. > > you can also use command: > > locate libm.* > > and then list all the contents here that would help rule out environmental > setup as the cause of the failed build. > > If you do either of these two things I can diagnose where the problem is. > > Also, after you have done that, try this command in that same shell: > > > sudo updatedb > > > that updates the /var/lib/plocate/plocate.db database used to locate > files.
