NETPBM and astrometry.cfg problems

[David Wyrick]

Hello,

I'm to the point where I don't know what else to do. I'm trying to run Astrometry.net on cygwin and after much frustration, I'm fairly certain I have all of the packages I need to move forward. Alas, netpbm is still not working.

I've followed the build instructions, make/make py/make extra/make install to the point where I have the Astrometry.net executables. 

my util/makefile.netpbm is

NETPBM_INC = -l/usr/local/netpbm/include

NETPBM_LIB = /usr/local/netpbm/lib/libnetpbm.a

I'm not sure this is the correct syntax, but from what I was seeing on this blog I figured it was correct

and I've exported that to environment variables as well...

so I make reconfig

$ make reconfig

rm -f '../include/astrometry/'os-features-config.h makefile.os-features

and then make 

$  make makefile.os-features

Makefile:61: makefile.os-features: No such file or directory

---- Error messages in the next few commands are not necessarily bugs ----

     (we're checking how things works on your computer)

rm -f os-features-makefile.log

Testing netpbm...

   NETPBM_INC_ORIG is -l/usr/local/netpbm/include

   NETPBM_LIB_ORIG is /usr/local/netpbm/lib/libnetpbm.a

--------------- End of expected error messages -----------------

mv makefile.os-features.tmp makefile.os-features

Config results:

------------------------------

cat makefile.os-features

# This file is generated by util/Makefile.

# Astrometry.net didn't find netpbm; not setting HAVE_NETPBM.

# See os-features-makefile.log for details.

# To re-run this test, do 'make reconfig; make makefile.os-features' (in the 'util' directory)

# Or to do it yourself, just uncomment this line:

# HAVE_NETPBM := yes

------------------------------

And, by the way, is WCSlib support being compiled in?

pkg-config --exists wcslib && echo yes || echo no

no

  WCSLIB_INC:

  WCSLIB_LIB:

------------------------------

make: 'makefile.os-features' is up to date.

This all started because I was getting error messages when I tried to solve-field test images.

The astrometry.cfg file has my filepath to the index files, but solve-field says it failed to open index directory. 

Help me, you're my only hope.

Hello,

Please check that you have Netpbm installed in cygwin. Look for the file /usr/include/netpbm/pam.h 

If it doesn't exist, you must run your Cygwin setup.exe program (mine is in the Windows Downloads folder, get it from https://cygwin.com/setup-x86.exe (32bit) or https://cygwin.com/setup-x86_64.exe (64bit)

When you run the setup program and you are given a choice of packages to install you need the following 

libnetpbm-devel

libnetpbm10

netpbm

Then, in util/makefile.netpbm you put

NETPBM_INC= -I /usr/include/netpbm

NETPBM_LIB ?= -lnetpbm

Cheers,

Themos

Themos,

Yes, the netpbm packages you listed were selected during install. After install Libnetpbm.a was simple in the C:/cygwin64/lib folder and the headers were in in C:/cygwin64/usr/include/netpbm, but I copied them over to a usr/local/netpbm/ folder.  

my util/makefile.netpbm is

NETPBM_INC = -l/usr/local/netpbm/include

NETPBM_LIB = /usr/local/netpbm/lib/libnetpbm.a

I'm statically linking the library because dynamic linking isn't working. Do these variables need to be the full path? with cygdrive/c/...

Thanks,

David

NETPBM_INC is the path to the headers.  It must start with -I, not -l.  Those characters look identical in the font I have.  It must be a capital letter i, I, not lower case ell.  It's a command to gcc that says "look for Include files here".

cheers,

Dustin,

It was as simple as a syntax error! :/ Thanks for pointing that out for me. I'm still fairly new to command line, cygwin especially. 

Cheers,

David
