问题
I have RHEL 6.5 Server with an installation of R (3.1.1) & RStudioServer (0.98.1062)
I have postgresql-9.3 installed and handling a large database. In order to connect R to PostgreSQL, I have in the past used the RPostgreSQL (still do on my CentOS 7 Workstation). However, attempting to compile under RHEL 6.5 I get an error
In file included from RS-PQescape.c:7:
RS-PostgreSQL.h:23:26: error: libpq-fe.h: No such file or directory
The file is located on my system here:
/usr/pgsql-9.3/include/libpq-fe.h
Libpq is part of the Postgres installation, but RPostgreSQL cannot find it:
[root@server /]# yum list libpq*
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
Installed Packages
libpqxx.x86_64 1:4.0.1-1.rhel6 @pgdg93
libpqxx-debuginfo.x86_64 1:4.0.1-1.rhel6 @pgdg93
libpqxx-devel.x86_64 1:4.0.1-1.rhel6 @pgdg93
Is there any way to tell RPostgreSQL where to look (symbolic links?) or some other workaround? This should be simple, but I've wasted several hours on this already...
回答1:
Followup info because I just had the same problem.
Installing yum install postgresql-devel resolves the error too.
回答2:
I ended up looking into the RPostgreSQL configure file in the tarball, searched for the file name the script couldn't find and decided it was easiest to create an environmental variable:
export PG_INCDIR=/usr/pgsql-9.3/include/
Worked like a charm after that.
If you have sudo rights, you could also try:
yum install postgresql-devel
