My copy of libusb-win32 0.1.12.2-1 does not have the symbol usb_debug in either the .h file or the shared library. Could someone review the change to usrp_libusb.m4 and see if it could be made to function again under Cygwin? Or explain why the change was made so someone else (like me?) can suggest an alternative? In the meanwhile you can work around the problem by modifying config/usrp_libusb.m4 to omit the check for usb_debug then rerunning ./bootstrap. -- Don W. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] Gnuradio build on cygwin failed with usrp
Updated git repository on my cygwin(1.7.7-1)+winxp box this weekend and tried rebuild gnuradio ./configure reported usrp is not to be built due to not able to detect libusb I do have libusb-win32 0.1.12.2-1 in cygwin Looked at the config.log, I found it insists on checking pkgconfig file libusb.pc, which does not exist. I manually created that file. Then it goes a bit further. configure:24742: Checking for LIBUSB version 'libusb' configure:24890: checking for USB configure:24898: $PKG_CONFIG --exists --print-errors "${libusb_name}" configure:24901: $? = 0 configure:24946: $PKG_CONFIG --exists --print-errors "${libusb_name}" configure:24949: $? = 0 configure:24966: $PKG_CONFIG --exists --print-errors "${libusb_name}" configure:24969: $? = 0 configure:25017: result: yes configure:25039: checking libusb for header usb.h configure:25054: gcc -c -I/usr/include conftest.c >&5 configure:25054: $? = 0 configure:25060: result: yes configure:25089: checking libusb for function usb_bulk_write in library usb configure:25107: gcc -o conftest.exe conftest.c -lusb >&5 configure:25107: $? = 0 configure:25114: result: yes configure:25136: checking libusb for symbol usb_debug in library usb configure:25150: gcc -o conftest.exe -I/usr/include conftest.c -lusb >&5 /tmp/ccaJXA3I.o:conftest.c:(.text+0x2c): undefined reference to `_usb_debug' I really don't know how that can be failed? checked the libusb-win32 source codes that usb_debug is indeed in usb.c I feel gnuradio support in cygwin is becoming more and more fragile. anyone has success in building usrp in cygwin recently?
