[Buildroot] problem compiling host-tiff-4.6.0

[Buildroot] problem compiling host-tiff-4.6.0

[Ralf Dragon]

Dear all,

for me in current master and 2024.02.x branches, the package 
host-tiff-4.6.0 fails to compile with:

...

libtool: link: /usr/bin/gcc -O2 
-I/home/dragon/src/ft/ftcommunity-TXT/output/build/rootfs/per-package/host-tiff/host/include 
-Wall -W -Wl,-rpath 
-Wl,/home/dragon/src/ft/ftcommunity-TXT/output/build/rootfs/per-package/host-tiff/host/lib 
-o tiffcp tiffcp.o 
-L/home/dragon/src/ft/ftcommunity-TXT/output/build/rootfs/per-package/host-tiff/host/lib 
../libtiff/.libs/libtiff.so ../port/.libs/libport.a -lLerc -ljbig -lm 
-Wl,-rpath 
-Wl,/home/dragon/src/ft/ftcommunity-TXT/output/build/rootfs/build/host-tiff-4.6.0/libtiff/.libs 
-Wl,-rpath 
-Wl,/home/dragon/src/ft/ftcommunity-TXT/output/build/rootfs/per-package/host-tiff/host/lib
/usr/bin/ld: ../libtiff/.libs/libtiff.so: undefined reference to 
`deflateInit_'
/usr/bin/ld: ../libtiff/.libs/libtiff.so: undefined reference to `deflate'
/usr/bin/ld: ../libtiff/.libs/libtiff.so: undefined reference to 
`deflateEnd'
/usr/bin/ld: ../libtiff/.libs/libtiff.so: undefined reference to `inflate'
...


It seems that the following diff fixes the problem, but I guess that the 
HOST_TIFF_CONF_OPTS were added in 91b16f for a reason and that the 
problem is a different.

--- a/package/tiff/tiff.mk
+++ b/package/tiff/tiff.mk
@@ -23,7 +23,6 @@ TIFF_DEPENDENCIES = host-pkgconf

  HOST_TIFF_CONF_OPTS = \
         --disable-cxx \
-       --disable-zlib \
         --disable-libdeflate \
         --disable-lzma \
         --disable-jpeg \

Could someone advise what to do?

Ralf

Thanks for the heads up, reproduced here.

Indeed. If you look closely to the failing line you see that you are
linking host-tiff with -lLerc and -ljbig. Presumably you have the
development packages for those libraries installed on your build host?

I have sent a series to explicitly disable lerc and jbig support in
tiff, which should fix the issue:
