[avrdude-dev] configure does not detect libftdi correctly in mingw

[Turbo J]

Hi,

using bare ./configure in MingW32/Msys results in:
[...]
checking for usb_get_string_simple in -lusb... yes
checking for libusb_init in -lusb-1.0... no
checking for libusb_init in -lusb... no
checking for ftdi_init in -lftdi... no

Looking in config.log shows the reason:
[...]
configure:5085: checking for ftdi_init in -lftdi
configure:5110: gcc -o conftest.exe -g -O2   conftest.c -lftdi   >&5
[ ... bunch of Linker errors follows ...]

The correct linker commands would have been
"-lftdi -lusb", it looks like there is no checks for
$ libftdi-config --libs
-L/mingw/lib -lftdi -lusb

Workaround:
$ export LIBS=-lusb ; ./configure

This enables libftdi usage for me.
