[Simulavr-devel] Build failures on Cygwin

[Petr Hluzín]

Hello

I tried to build the newest simulavr (from Git) and the build failed:

$ make

Help 'configure --help' indicates option --without-PACKAGE, so I tried:
$ ./configure --without-libbfd
...
configure: WARNING: unrecognized options: --without-libbfd
Summary:
build system = Cygwin
AVR_GCC=avr-gcc
AVR_LIBBFD_INC=/usr/include
AVR_LIBBFD_LIB=/usr/lib/libcygwin.a /usr/lib/libbfd.a
AVR_LIBIBERTY_LIB=/usr/lib/libiberty.a /usr/lib/libintl.a /usr/lib/libiconv.a
PYTHON=/usr/bin/python
TCL_WISH=/usr/bin/wish
tcl has package Itcl? no
build verilog modul avr.vpi = no

And therefore it still failed.

Then I tried to edit ./src/Makefile and friends to get rid of the libbfd.a:
-AVR_LIBBFD_LIB = /usr/lib/libcygwin.a /usr/lib/libbfd.a
+AVR_LIBBFD_LIB =
but the 'make' still managed to obtain the value somehow.

Search on Internet suggested disabling internationalization by
--disable-nls. The same results.

I just want it to build. I can disable the BFD specific code in
simulavr (i.e. AvrDevice::Load) and live without it if it builds.

Does anyone know how to remove libbfd.a from linking?
Or how to solve the "undefined reference to `_libintl_dgettext'"?

I cannot test my changes for unix-like systems.
