Issue
No clue why this: pkg-config proj --libs
gives: -lproj
when it should be: -L/usr/lib/x86_64-linux-gnu -lproj
because proj.pc is in /usr/lib/x86_64-linux-gnu/pkgconfig/
Now, is this problem related to proj_api.h not found in standard or given locations? My LMint 20.1 does not find that. I keep getting:
PROJ header location specified: -I/usr/include - check if proj_api.h is there...
checking proj_api.h usability... no
checking proj_api.h presence... no
checking for proj_api.h... no
configure: error: Did not find PROJ headers according to --with-proj-include - check the installation!
Even though proj_api.h is here:
$ locate proj_api.h
/usr/include/proj_api.h
Is this a problem with PROJ4 version 7.2.1-1? I found some posts about this (eg. this one about PKG_CONFIG_PATH in .bashrc) but no solutions. Any help is much appreciated,
-- PROJ4 version:
ii libproj-dev:amd64 7.2.1-1~focal0 amd64 Cartographic projection library (development files)
ii libproj19:amd64 7.2.1-1~focal0 amd64 Cartographic projection library
ii proj-bin 7.2.1-1~focal0 amd64 Cartographic projection library (tools)
ii proj-data 7.2.1-1~focal0 all Cartographic projection filter and library (datum package)
Solution
Found it, the solution is to put ACCEPT_USE_OF_DEPRECATED_PROJ_API_H=1 before the configure call like this:
sudo CFLAGS="-I/usr/include -DACCEPT_USE_OF_DEPRECATED_PROJ_API_H=1" ./configure --prefix=/home/gery/misProgramas/mb/mbsystem-trunk.r2346 --with-gmt-config=/home/gery/misProgramas/gmt/gmt-5.4.4/bin --with-otps-dir=/home/gery/misProgramas/mb/OTPS2
