[Ur] Trouble getting started. Link errors.

[Steve Sims]

Hello.  I have been watching Ur/Web for a while with great interest and
finally found
some time to kick the tires.  Unfortunately, I hit the same error that was
reported on
the list in November:

$ urweb simsnet
/tmp/fileEazvG0/webapp.o: In function `uw_cookie_sig':
webapp.c:(.text+0xd4): undefined reference to `uw_hash_blocksize'

webapp.c:(.text+0x1a9): undefined reference to `uw_mayReturnIndirectly'
webapp.c:(.text+0x1b9): undefined reference to `uw_set_script_header'
...

I could not find a resolution to this issue.  Was it ever figured out?

Here is what I did to get here.

I am using a fresh Ubuntu 11.10 install.

According to the install instructions from the Ur/Web manual I installed
required packages:

$ sudo apt-get install openssh-server
$ sudo apt-get install mlton libssl-dev
$ sudo apt-get install libpq-dev
$ sudo apt-get install postgresql

I downloaded and unziped the latest Ur/Web source distribution (20111127)

Did:
$ ./configure
...
Ur/Web configuration:
  bin directory:       BIN            /usr/local/bin
  lib directory:       LIB            /usr/local/lib/urweb
  include directory:   INCLUDE        /usr/local/include/urweb
  site-lisp directory: SITELISP
/usr/local/share/emacs/site-lisp/urweb-mode
  C compiler:          CC             gcc
  Extra CC args:       CCARGS
  Postgres C header:   PGHEADER       postgresql/libpq-fe.h
  MySQL C header:      MSHEADER       mysql.h
  SQLite C header:     SQHEADER       sqlite3.h

  Version:             20111127

$ make
make  all-recursive
make[1]: Entering directory `/home/steve/urweb'

$ sudo make install

Seems to go through fine.  Puts libraries in /usr/local/lib

In the previous thread Adam said the missing symbols are from liburweb.so
which seems to be in /usr/local/lib with appropriate permissions:

12:10 urweb

In the previous thread Adam also suggested the -debug flag to see the gcc
command line. I get:

gcc -pthread -Wimplicit -Werror -Wno-unused-value -I
/usr/local/include/urweb -c /tmp/webapp.c -o /tmp/webapp.o -g gcc -Werror
-lm -pthread -L/usr/local/lib/urweb/.. -lurweb -lurweb_http -lssl -lcrypto
/tmp/webapp.o -o /home/steve/simsnet/simsnet.exe -g

which seems to be pointing to the right directory via
-L/usr/local/lib/urweb/..

The only other thing I can think to mention is that Ubuntu 11.10 seems to
be using gcc version 4.6.

Any help would be greatly appreciated. I would love to play around with
Ur/Web if I can get going.

Best Regards,
Steve
