library path(s) and subfolders within

Thanks!

Does the -L option ensure the sub-directories are searched recursively?

The -lhtslib-1.10.2 option of your command line may be wrong in this case as htslib-1.10.2 is a folder under which there are several sub-folders and many *.c *.h *.o *.pico files, but I understand your point. Two files: libhts.so and libhts.a may be the ones I need(permission is checked to be correct). So I tried:
Code:
$ gcc -Wall -O3 -o vcf_parser01 vcf.c vcf_parser01.c  -Wl,-rpath,/home/yifangt/Study/C/VCF  -L/home/yifangt/Study/C/VCF/htslib-1.10.2 -lhts 

  /tmp/ccSYd2K4.o: In function `bcf_hdr_set_idx.isra.10':
vcf.c:(.text+0x11d5): undefined reference to `hts_resize_array_'
/tmp/ccSYd2K4.o: In function `vcf_hdr_read':
vcf.c:(.text+0x66ad): undefined reference to `tbx_index_load3'
/tmp/ccSYd2K4.o: In function `vcf_write':
vcf.c:(.text+0xd57a): undefined reference to `hts_idx_tbi_name'
/tmp/ccSYd2K4.o: In function `bcf_index_load3':
vcf.c:(.text+0xdd55): undefined reference to `hts_idx_load3'
/tmp/ccSYd2K4.o: In function `bcf_idx_save':
vcf.c:(.text+0xe181): undefined reference to `sam_idx_save'
collect2: error: ld returned 1 exit status

Under the htslib-1.10.2 folder, there are three sub folders cram/, htslib/ and m4/ that may be involved.

In htslib/ sub-folder, *.h files only, so that's for the headers;
In cram/ and m4/ sub-folders, there are *.c, *.h and *.o files (and some other types, which seems for portability, and may not be needed, very likely to me!);
Also I have tried archive the *.o files into library in the format as mylibx.a or mylibx.so files, the error stayed the same. I have attached the link to download the library and my src code. Could it be possible for you to download the library to have a look at the code? That may be easier than what I explained.
Thanks a lot.

WMANAGER(1)						    BSD General Commands Manual 					       WMANAGER(1)

NAME
wmanager -- choose a window manager and launch it SYNOPSIS
wmanager [OPTIONS ...] DESCRIPTION
The wmanager program displays a choice of the window managers listed in the ~/.wmanagerrc file. When one is picked, the related command is written to standard output, intended to be used by shell scripts. If the program is exited without choosing a window manager, ``-1'' is written to standard output. -fg COLOR Set the foreground color. -bg COLOR Set the background color. -bg2 COLOR Set the widget background color -di[splay] host:n.n Set the X display. -dn[d], -nod[nd] Enable/disable drag & drop, probably does nothing. -g[eometry] WxH+X+Y Set the window size and location. -i[conic] Start as iconified. -k[bd], -nok[bd] Enable/disable keyboard support. -na[me] CLASSNAME Set the X window class. -s[cheme] SCHEME Unknown, probably does nothing useful. -ti[tle] WINDOWTITLE Set the window title. -to[oltips], -not[ooltips] Enable/disable tooltips, probably does nothing. EXAMPLE
To start using wmanager, create a ~/.wmanagerrc file - generally with wmanagerrc-update(1) - and add something like the following at the end of your ~/.xsession file: WM="$(wmanager -geometry +570+585)" ... exec $WM See also wmanager-loop(1) for a nicer way to start wmanager. SEE ALSO
