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.

scdsbuilder

scdsbuilder(1HA)					       Sun Cluster Commands						  scdsbuilder(1HA)

NAME

       scdsbuilder - launch GUI version of Sun Cluster Agent Builder

SYNOPSIS

       scdsbuilder

DESCRIPTION

       The scdsbuilder command launches the GUI version of the Sun Cluster Agent Builder.

       Before you use Agent Builder, verify the following requirements:

	   o	  The  Java  runtime  environment is included in your $PATH variable.  Agent Builder depends on the Java Development Kit, starting
		  with Version 1.3.1.  If the Java Development Kit is not included in your $PATH variable, the Agent Builder command (scdsbuilder)
		  returns and displays an error message.

	   o	  You have installed the Developer System Support software group of the Solaris 9 OS or Solaris 10 OS.

	   o	  The  cc  compiler  is  included  in your $PATH variable. Agent Builder uses the first occurrence of cc in your $PATH variable to
		  identify the compiler with which to generate C binary code for the resource type. If cc is not included in $PATH, Agent  Builder
		  disables the option to generate C code.

       Note -

	 You can use a different compiler with Agent Builder than the standard cc compiler. To use a different compiler, create a symbolic link in
	 $PATH from cc to a different compiler, such as gcc. Or, change the compiler specification in the makefile (currently, CC=cc) to the  com-
	 plete path for a different compiler. For example, in the makefile that is generated by Agent Builder, change CC=cc to CC=pathname/gcc. In
	 this case, you cannot run Agent Builder directly. Instead, you must use the make and make pkg commands to generate data service code  and
	 the package.

EXIT STATUS

       This command returns the following exit status codes:

       0		   The command completed succesfully.

       nonzero		   An error occurred.

FILES

       install_directory/rtconfig	   Contains  information  from	the  previous  session.  This  information facilitates the tool's quit and
					   restart feature.
