allow me to work around this.
But I cannot find that option anywhere. Is it in the ecospro repo only?
This is only in ecosCentric's closed source port :-(
<ahem> That's not closed source. It's under the usual eCos licence,
distributed as per 3(a) of the GPL.
A shame really,
libsupc++.a regularly causes problems for synth, so being able to get
rid of this dependancy would be good.
Copy the relevant subset of source files from GCC's libsupc++ into the
synth HAL (probably in a subdir), build it into its own library (compile
-library=libsupc++-ecos.a .... ?) and use that instead of libsupc++ in the
linker script. The synth HAL can use CDL requires on
CYGBLD_HAL_LINKER_GROUPED_LIBS_DEFAULT to do this (a newly added option,
part of a contribution by eCosCentric :-)).
It's probably safer in its own library due to its slightly different GPL
exception wording at the top.
