i'm trying to build dm-postgres-adapter but get this error.
sudo gem install dm-postgres-adapter
Building native extensions. This could take a while...
ERROR: Error installing dm-postgres-adapter:

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
installing pg
worked after installing postgresql and setting pg_config path
`bundle config build.pg --with-pg-config=/usr/local/Cellar/postgresql/9.3.1/bin/pg_config`
what i am absolutly confused about is that postgres.h
is found, but not pg_wchar.h which is in the same directory /usr/local/Cellar/postgresql/9.3.1/include
setting configuration options doesnt help
--with-pgsql-server-include=/usr/local/Cellar/postgresql/9.3.1/include
i've tried this with macports postgresql before. after having the same error i've completly uninstalled mac ports and install postgresql with homebrew. I also tried the postgresql package Postgres.app
but i get always the this error.
as i said before installing pg (gem) worked.
mkmf.log
as said in error message - "Check the mkmf.log file for more details."
this makes absolutely no sense to me.
conftest.c:5:57: error: use of undeclared identifier 'main'
int t(void) { void ((*volatile p)()); p = (void ((*)()))main; return 0; }
1 error generated.
checked program was:

2:

4: extern int t(void);
5: int t(void) { void ((*volatile p)()); p = (void ((*)()))main; return 0; }

but...
this one
/usr/local/Cellar/postgresql/9.3.1/include/server/mb/pg_wchar.h:363:14: error: function
cannot return function type 'int (unsigned char *, int)'
typedef bool (*mbcharacter_incrementer) (unsigned char *mbstr, int len);
^
/usr/local/Cellar/postgresql/9.3.1/include/server/mb/pg_wchar.h:388:2: error: unknown type
name 'uint32'
... and lot of "unknown type name 'uint32' ...
pg_wchar.h is found!!!! yeah! but wait there is an error.
fixed it with
typedef uint32_t uint32; // added in pg_wchat.h
but then comes the next
/usr/local/Cellar/postgresql/9.3.1/include/server/mb/pg_wchar.h:364:14: error: function
cannot return function type 'int (unsigned char *, int)'
typedef bool (*mbcharacter_incrementer) (unsigned char *mbstr, int len);
yes, i could go this through and trying to fix it, but i don't think that this is the right way
i have absolutely no idea where to go on. So if somebody could help i would appreciate it.
ps: i am using mac os mavericks
I fixed this.
I wish I could give exact steps, but it was something like this:
Manually updated Command Line Tools from the apple developer site.
Uninstalled all gems
Installed rbenv, ruby-build, rbenv-bundler using brew
Installed apple-gcc42 using brew
Installed ruby 2.1 using rbenv
Set path to use rbenv's ruby.
Set rbenv global 2.1.0
Uninstalled bundle
Installed bundle
ran rbenv rehash
Ran sudo bundle install
successfully.
from brew info postgres, try setting ARCHFLAGS when building the gem. something like
ARCHFLAGS="-arch x86_64" gem install pg
or
ARCHFLAGS="-arch x86_64" gem install dm-postgres-adapter
and see if that helps.
