Top Forums Programming How to make use others' C library installed not for the system-wide (Ubuntu/Linux)? Post 303042977 by Neo on Wednesday 15th of January 2020 12:04:38 AM

First, I suggest when troubleshooting, you should:

Use the full path name to file, not relative path name. This will insure there are no strange, unseen PATH issues. For example:

Code:
gcc -Wall -O3 -I ./htslib-1.10.2/htslib  -o vcf_parser01 vcf.c  vcf_parser01.c

I would change this to:

Code:
gcc -Wall -O3 -I /FULL/PATH/TO/HERE/htslib-1.10.2/htslib  -o vcf_parser01 vcf.c  vcf_parser01.c

Second, you should confirm that these objects are in the PATH, exactly, and that you have read / access permission for them.

Sometimes, even the best sys admins install code under one userid, then they work as another userid, and they do not have permissions to access the file. Happens all the time (at least to me, LOL).

This is generally the first two steps I always take (back to basics, before back to the future).
  • Insure your PATH(s) are correct and objects / symbols are in the PATH(s), correctly.
  • Check file and directly permissions for the userid you are using to build.

UNIX and Linux are funny things, they generally do what they are told to do and report back the "facts" as they find them. In your case, gcc cannot find required symbols and objects. This is generally because they cannot find them, i.e. not in the search PATH or the file/directory permissions are "not as required".

Please post back and let me know if you are certain your PATHs are correct and why, using the FULL PATH names to files and directories in your command line for gcc.

Since we are not "standing behind you, watching you type", we cannot "see" what directory you are in, so to be sure, it is always best to use FULL PATH names when troubleshooting a problem like this.

Thanks.

AA-EASYPROF(8)							     AppArmor							    AA-EASYPROF(8)

NAME
aa-easyprof - AppArmor profile generation made easy. SYNOPSIS
aa-easyprof [option] <path to binary> DESCRIPTION
aa-easyprof provides an easy to use interface for AppArmor policy generation. aa-easyprof supports the use of templates and policy groups to quickly profile an application. Please note that while this tool can help with policy generation, its utility is dependent on the quality of the templates, policy groups and abstractions used. Also, this tool may create policy which is less restricted than creating policy by hand or with aa-genprof and aa-logprof. OPTIONS
aa-easyprof accepts the following arguments: -t TEMPLATE, --template=TEMPLATE Specify which template to use. May specify either a system template from /usr/share/apparmor/easyprof/templates or a filename for the template to use. If not specified, use /usr/share/apparmor/easyprof/templates/default. -p POLICYGROUPS, --policy-groups=POLICYGROUPS Specify POLICY as a comma-separated list of policy groups. See --list-templates for supported policy groups. The available policy groups are in /usr/share/apparmor/easyprof/policy. Policy groups are simply groupings of AppArmor rules or policies. They are similar to AppArmor abstractions, but usually encompass more policy rules. -a ABSTRACTIONS, --abstractions=ABSTRACTIONS Specify ABSTRACTIONS as a comma-separated list of AppArmor abstractions. It is usually recommended you use policy groups instead, but this is provided as a convenience. AppArmor abstractions are located in /etc/apparmor.d/abstractions. See apparmor.d(5) for details. -r PATH, --read-path=PATH Specify a PATH to allow owner reads. May be specified multiple times. If the PATH ends in a '/', then PATH is treated as a directory and reads are allowed to all files under this directory. Can optionally use '/*' at the end of the PATH to only allow reads to files directly in PATH. -w PATH, --write-dir=PATH Like --read-path but also allow owner writes in additions to reads. -n NAME, --name=NAME Specify NAME of policy. If not specified, NAME is set to the name of the binary. The NAME of the policy is often used as part of the path in the various templates. --template-var="@{VAR}=VALUE" Set VAR to VALUE in the resulting policy. This typically only makes sense if the specified template uses this value. May be specified multiple times. --list-templates List available templates. --show-template=TEMPLATE Display template specified with --template. --templates-dir=PATH Use PATH instead of system templates directory. --list-policy-groups List available policy groups. --show-policy-group Display policy groups specified with --policy. --policy-groups-dir=PATH Use PATH instead of system policy-groups directory. --author Specify author of the policy. --copyright Specify copyright of the policy. --comment Specify comment for the policy. EXAMPLE
Example usage for a program named 'foo' which is installed in /opt/foo: $ aa-easyprof --template=user-application --template-var="@{APPNAME}=foo" --policy-groups=opt-application,user-application /opt/foo/bin/FooApp BUGS
