[Bug-wget] [bug #50223] wget 1.19 will not build on MacOS 10.12.3

[Zhiming Wang]

Follow-up Comment #11, bug #50223 (project wget):

The commit to add wcwidth to bootstrap.conf did not help me, but upon further
investigation, I realized that it was because I have libunistring installed
(which, if linked, provides uc_width); if I move libunistring out of the way,
I have no problem with compilation. Therefore, this may not be a problem for
most users.

That said, the libunistring problem is a weird one. configure does check for
libunistring:


./configure | grep libunistring
checking whether included libunistring is requested... no
checking for libunistring... yes
checking how to link with libunistring... -L/usr/local/lib -lunistring
checking for libunistring version... 0.9.7
checking whether to use the included libunistring... no


but it doesn't set the proper ld flags:


$ grep LIBUNISTRING= config.log
HAVE_LIBUNISTRING='yes'
LIBUNISTRING=''
LTLIBUNISTRING=''


(the above should instead be:


$ grep LIBUNISTRING= config.log
HAVE_LIBUNISTRING='yes'
LIBUNISTRING='-L/usr/local/lib -lunistring'
LTLIBUNISTRING='-L/usr/local/lib -lunistring -R/usr/local/lib'


)

Interestingly, I created a dummy project where I ran


gnulib/gnulib-tool --import libunistring-optional


then with boilerplate configure.ac and automake.am, the generated configure
would set LIBUNISTRING and LTLIBUNISTRING to the correct values. Not sure
where the problem is.
