A FreeBSD update forces me to run Xmonad by cabal-install. After I run "cabal new-update"
I find that it audaciously placed a 636MB file inside the directory "~/.cabal". Having a closer look I noticed that this is the unzipped version of a .tar.gz of 85MB.
Question #1: How can I inhibit to unpack this monster?
Question #2: I am loggin in as two different users. Is there a way to install the zipfile in a global place?
Thanks in advance,
Bertram
You can't inhibit the unpacking of it. Cabal needs it to operate. That said, your solution to how to replace it with a symlink seems fine.

I am trying to write a base type for PostgreSQL in C (using xcode), and I already installed PostgreSQL 11, but it seems that postgres.h cannot be simply included in the file ("'postgres.h' file not found").
Could someone tell me how to fix that problem? And can I write code under an arbitary directory, or do I have to write under the PostgreSQL directory?
Or perhaps the question should be: how to install header files like postgres.h?
Install postgresql-server-dev package with this command:
sudo apt install postgresql-server-dev-XX
Replace [XX] with your already installed version of postgresql:9.5, 10, 11, 12
You have several approaches here:
Search for the file yourself, using some command like
find / -name "postgres.h" -print
this will tell you (on my Mac does) the file is in:
/usr/local/Cellar/postgresql/11.2_1/include/server/postgres.h
and add the -I /usr/local/Cellar/postgresql/11.2_1/include/server option to the compiler. Check your postgresql version for the possibility of having a different one.
Probably there's another package for database development. Search for a package named postgresql-dev or similar, and install it. After searching packages with:
brew search postgres
and
brew search psql
on my system doesn't appear anything that matches.
EDIT
I've checked a FreeBSD system for that file and it appears on
/usr/local/include/postgresql/server/postgres.h
So probably you have to #include <server/postgres.h> instead, and use the appropiate -I flag (as mentioned above)
I was facing the same issue while compiling postgis 3.1.7 for postgresql#13 on my Mac.
The problem was that in pg_config the link to server file was
/opt/homebrew/opt/postgresql#13/include/server
While the actual server folder was in
/opt/homebrew/opt/postgresql#13/include/postgresql/server
So I moved the entire "server" folder up a directory inside "/include". And viola, postgis compiled and installed perfectly.
The simple directions found all over the internet for installing Core using OPAM no longer work. What is the new way to install and use Core?
I think I tracked the problem down to a message on the ocaml-core mailing list about renaming several dependencies https://groups.google.com/forum/#!topic/ocaml-core/Te6LTiNBO08.
Paired down, the widely published installation instructions amount to two steps after installing opam itself:
$ opam install core
$ cat >> ~/.ocamlinit <<EOF
#use "topfind";;
#thread;;
#camlp4o;;
#require "core.top";;
#require "core.syntax";;
EOF
Following these directions result in an error about the "sexprlib.syntax" package missing when using ocaml (or corebuild, utop, etc).
Failing directions can be found in this widely referenced ebook
https://github.com/realworldocaml/book/wiki/Installation-Instructions#setting-up-and-using-utop
and are reflected in directions here on Stackoverflow in questions such as:
Ocaml utop library paths, Core module
What is the new way to set up Core?
opam install core no longer seems to be sufficient since it does not pull in the new syntax packages. I am not sure if this is a dependency bug or not.
The recommended ocamlinit settings also seem wrong.
I found that the core 113.24.00 is defective and all the installation instructions on the net as of this writing are out of date.
Users must make the following corrective steps:
Remove all #require references to packages ending in .syntax from ~/.ocamlinit.
Make your own corebuild script without any references to syntax packages
as found at https://github.com/janestreet/core/blob/master/corebuild.
You may also remove the #camlp4o;; line from your .ocamlinit as this library is no longer required by Core.
I'm working on an package for GNU Octave. One of the package functions uses a large, pre-computed table of data. That data is stored in a mat file which I load and unload when the function is called. The problem is that I'm unsure of a good, installation non-specific way of doing this. As near as I can tell I have to give the load command an absolute path to the mat file within the package install directory. I can see no way of getting that directory at run-time. Am I missing something or am I just going about this the wrong way?
PKG_ADD is executed when the package is loaded so you can get the path where PKG_ADD resides in with __fqp__ = fileparts (mfilename ("fullpath"));From there you can init your data.
If you want the install dir from another package it's possible to load( pkg ("local_list")) and inspect local_packages.
I also think such specific Octave questions should go to the help#octave.org mailinglist.
Do you want to distribute your new package on octave-forge?
Here my package is net-snmp.
Here is the task : Addition of Net-SNMP Source directory at path personal/apps/snmp/
Requirement is that it should download from website if there is change in version name and it should patch , configure and build soruce.
Hence, for that we need to configure Config.in and netsnmp.mk files in build/package/netsnmp in order to fulfill this requirement.
By adding following configuration in netsnmp.mk
NETSNMP_VERSION = 5.7.2.1
NETSNMP_SOURCE = net-snmp-$(NETSNMP_VERSION).tar.gz
NETSNMP_SITE = http://www.sourceforge.net/projects/net-snmp/files/net-snmp/$(NETSNMP_VERSION)
We can download the latest net-snmp tar ball which will be downloaded in dl/ folder in buildroot.
From here it will untar in build/output/build and will patch configure and build. After that it will build the executable at appropriate location inside target folder.
Here the issue is I want netsnmp source code to be at personal/apps/snmp folder which seems to be problematic and can edit the source in path personal/apps/snmp/ and configure build from here.
Any help and suggestion will be appreciated.
There is already a netsmp package in Buildroot. Why do you want to create another one?
Also, the Buildroot community is going to be much more reactive if you ask questions on the project's mailing list.
I am attempting to run foswiki on OpenBSD. Things are installed and i am able to open "/bin/Configure" page of foswiki configuration screen. but the page reports few errors, complaining that following files are either not found or outdated and new versions are required.
The Files are : grep, rcs, ci, co,rlog, rcsdiff
I tried commands like "pkg_add -Uu" to upgrade packages installed, but it reports all packages are uptodate.
I also tried "pkg_add rcs" "pkg_add grep" etc but non works.
So my basic question is how to I update above files to their latest version required by foswiki.
Regards
While I’m not familiar with Foswiki, my first thought is your web server is chrooted, as this is the default on OpenBSD, and, as a result, Foswiki cannot find the files it needs. You can copy the files Foswiki needs into the chroot or run the web server without chroot, which is bad from a security perspective.
all programs mentioned are part of a base openbsd install and the above answer is correct. the openbsd documentation on chrooted apache has more info.
if you don't have to stick with foswiki you can try dokuwiki instead which has package support on openbsd and installs easily in very much the same way you tried already:
sudo pkg_add -U dokuwiki
hope the process is pretty much self-descriptive. in addition, the manpage for pkg_add is a good thing to read. good luck!
