I have a function for generating tags via ctags:
:function! UpdateCtags()
if !has('linux')
echohl ErrorMsg | echo 'This function only supports running under the linux operating system.' | echohl None
return
endif
echo 'Generating labels...'
let output = system('ctags -f ' . g:tags_file . ' -R /usr/include')
if v:shell_error == 0
echo 'Generated labels successfully.'
else
echohl ErrorMsg | echo output | echohl None
endif
:endfunction
I want to simply execute the UpdateCtags function through multiple threads, how can I do this?

I trying to enable AB OTA in AOSP11 source code.
Followed below steps:
Step 1:
BOARD_USES_AB_IMAGE := true
Step 2 : CONFIG_ANDROID_AB=y in u boot source code.
Getting below compilation error :

There is Swift compiler option -target:
$ swiftc -h
...
-target <value> Generate code for the given target
...
Where from can I get all possible values for compiler option -target (i.e: x86_64-apple-ios11.0, x86_64-apple-macosx10.12, ...) ?
Thanks!

I'm learning how to use HPC on our lab's clusters, which uses LSF. I tried a simple serial jobs each of which count the frequency of the words in a text file. I wrote a python code for counting the word frequency named count_word_freq.py, a jobs script named myjob.job as following:
python count_word_freq.py --in ~/books/1.txt --out ~/freqs/freq1.txt
python count_word_freq.py --in ~/books/2.txt --out ~/freqs/freq2.txt
python count_word_freq.py --in ~/books/3.txt --out ~/freqs/freq3.txt
python count_word_freq.py --in ~/books/4.txt --out ~/freqs/freq4.txt
python count_word_freq.py --in ~/books/5.txt --out ~/freqs/freq5.txt
and a lsf script to submit the serial jobs to the selfscheduler:
#!/bin/bash
#BSUB -J test01
#BSUB -P acc_pandeg01a
#BSUB -q alloc
#BSUB -W 20
#BSUB -n 20
#BSUB -m manda
#BSUB -o %J.stdout
#BSUB -eo %J.stderr
#BSUB -L /bin/bash
module load python
module load py_packages
module load selfsched
# And run the program; output will be on stdout
mpirun selfsched < myjobs001.jobs
The python code is as following:
def readBookAsFreqDict(infile):
dic = {}
with open(infile,"r") as file:
for line in file:
contents = line.split(" ")
for cont in contents:
if str.isalpha(cont):
if cont not in dic.keys():
dic[cont] = 1
else:
dic[cont] = dic[cont] + 1
return dic
import sys
import argparse
import time as T
if __name__ == "__main__":
start = T.time()
parser = argparse.ArgumentParser()
parser.add_argument('--i', type=str, help = 'input file')
parser.add_argument('--o', type=str, help = 'output file')
args = parser.parse_args()
dic = readBookAsFreqDict(args.i)
outfile = open(args.o,"w")
for key,freq in dic.iteritems():
outfile.write(key + ":" + str(freq) + "\n")
end = T.time()
print (end - start)
The 5 input texts are almost the same size of around 3.5 MB. My question is that the CPU time for running this serial job is 980s, which is worse than running it sequentially.
To my understanding, the selfscheduler can automatically assign the 5 jobs to empty nodes, thus can save the running time for running it sequentially. Is that because the execution time for each job is too short compared to the time to find an empty node? Is there any other approaches can be used to make it faster?
Thank you!
I wrote a SQL extension following the instructions on PGXN, but I always get a make install error as following:
/bin/mkdir -p '/usr/share/postgresql/9.5/extension'
/bin/mkdir -p '/usr/share/postgresql/9.5/extension'
/bin/mkdir -p '/usr/share/doc/postgresql-doc-9.5/extension'
/usr/bin/install -c -m 644 .//myextname.control '/usr/share/postgresql/9.5/extension/'
/usr/bin/install -c -m 644 .//sql/myextname--1.0.0.sql .//sql/myextname--1.0.0.sql '/usr/share/postgresql/9.5/extension/'
/usr/bin/install: will not overwrite just-created ‘/usr/share/postgresql/9.5/extension/myextname--1.0.0.sql’ with ‘.//sql/myextname--1.0.0.sql’
make: *** [install] Error 1
My Makefile is as following:
EXTENSION = myextname
EXTVERSION = $(shell grep default_version $(EXTENSION).control | \
sed -e "s/default_version[[:space:]]*=[[:space:]]*'\([^']*\)'/\1/")
DATA = $(filter-out $(wildcard sql/*--*.sql),$(wildcard sql/*.sql))
TESTS = $(wildcard test/sql/*.sql)
REGRESS = $(patsubst test/sql/%.sql,%,$(TESTS))
REGRESS_OPTS = --inputdir=test
DOCS = $(wildcard doc/*.md)
MODULES = $(patsubst %.c,%,$(wildcard src/*.c))
PG_CONFIG = pg_config
PG91 = $(shell $(PG_CONFIG) --version | grep -qE " 8\\.| 9\\.0" && echo no || echo yes)
ifeq ($(PG91),yes)
all: sql/$(EXTENSION)--$(EXTVERSION).sql
sql/$(EXTENSION)--$(EXTVERSION).sql: $(strip sql/tables.sql \
sql/types.sql \
sql/domains.sql \
)
cat $^ > $#
DATA = $(wildcard sql/*--*.sql) sql/$(EXTENSION)--$(EXTVERSION).sql
EXTRA_CLEAN = sql/$(EXTENSION)--$(EXTVERSION).sql
endif
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)
This blog says this error is caused by this line:
DATA = $(wildcard sql/*--*.sql) sql/$(EXTENSION)--$(EXTVERSION).sql
which evaluates into the same filename twice (and /usr/bin/install refuses to overwrite the first instance of the file).
But how can I fix it?
You seem to have copied the Makefile from PGXN, and it is probably much more complicated than you need.
For example, do you target PostgreSQL versions below 9.1?
You'll be much better off with a small, simple custom tailored Makefile like this:
MODULES = src/myextname
EXTENSION = myextname
DATA = sql/myextname--1.0.sql
DOCS = doc/myextname.md
REGRESS = myextname
REGRESS_OPTS = --inputdir=test
PG_CONFIG = pg_config
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)
This (untested) Makefile sticks with the file organization suggested by PGXN.
I'm trying to create a statically linked version of pngquant in Oracle Linux Server release 7.1. I've compiled the static version of zlib and the static version of libpng.
Then, when I configure pngquant, I always get the information that it will be linked with a shared version of zlib.
$ ./configure --with-libpng=../libpng-1.6.21 --extra-cflags="-I../zlib-1.2.8" --extra-ldflags="../zlib-1.2.8/libz.a"
Compiler: gcc
Debug: no
SSE: yes
OpenMP: no
libpng: static (1.6.21)
zlib: shared (1.2.7)
lcms2: no
If I execute make, in the output it seems that the options are correctly passed to the compiler. However, the resulting binary requires libz.so to be executed. It seems that my directives are ignored or that the installed version always takes precedence.
Is there any way of forcing pngquant to be compiled with the static version of zlib?
I'm not sure, if I got it right, but here's a patch to pngquant's configure that worked for me. configure now accepts --with-zlib=<dir> as parameter. Store it to pngquant.patch and apply it with patch -uN -p1 -i pngquant.patch.

Sorry, the configure script does not support it. It shouldn't be too hard to modify configure to pass appropriate flags to pkg-config or do the same workaround it does for libpng.
