This set of commands aren't working as they're supposed to:
mkdir -p /home/git/root_backup_folder
cd /home/git/gitlab/git-data/repositories
tar zcvf dailybackup.tar.gz * -C /home/git/root_backup_folder
It is completely ignoring the -C argument and creating the file in /home/git/gitlab/git-data/repositories. What I'm doing wrong?
The -C flag doesn't specify the output directory. You need to do this at the point at which you specify the archive file. So, your command could become:
tar zcvf /home/git/root_backup_folder/dailybackup.tar.gz *

I'm trying to compile the libpng 1.2.56 file and use a target.cc(same as fuzzer-test-suite to unite all these file in libpng1.2.56 into one LLVM IR bitcode file, named combined.bc.
Here is my compile process, refering build.sh:
[ ! -e libpng-1.2.56.tar.gz ] && wget https://downloads.sourceforge.net/project/libpng/libpng12/older-releases/1.2.56/libpng-1.2.56.tar.gz
[ ! -e libpng-1.2.56 ] && tar xf libpng-1.2.56.tar.gz
build_lib() {
rm -rf BUILD
cp -rf libpng-1.2.56 BUILD
(cd BUILD && ./configure --disable-shared && make -j $JOBS )
}
build_lib || exit 1
mkdir bitcode
clang++-10 -g -flto -std=c++11 ./target.cc -c -o bitcode/target.o -I .
cd bitcode
ar x ../.libs/libpng12.a
llvm-link-10 *.o -o combined.bc
And error is

The bitcode folder:

For modifications like the above, I succeeded on the project json, but not on libpng.
I am a beginner in LLVM and would like to get answers from you all. Thanks a lot!
So here is my Makefile file:
webgl:
emcc -s USE_SDL=2 -s USE_SDL_IMAGE=2 -s SDL2_IMAGE_FORMATS='["bmp","png", "jpeg", "jpg"]' -s USE_SDL_TTF=2 -c main.cpp -o build/index.o
emcc -O1 build/index.o -s LLD_REPORT_UNDEFINED -s ERROR_ON_UNDEFINED_SYMBOLS=0 -o build/index.js
Yes, I have been using SDL2 for my emscripten project and compiling it has the big error so I have added a -s LLD_REPORT_UNDEFINED -s ERROR_ON_UNDEFINED_SYMBOLS=0 to compile immediately without errors. After my attempt to build, it works but I can't run because of an error when I typed node index.js and pressing the Enter key.
missing function: _ZN4CoreC1Ev
Aborted(-1)
I searched up _ZN4CoreC1Ev on Google for solution but Your search - _ZN4CoreC1Ev - did not match any documents. it just said. Any solutions?
I need to add my own package to the openwrt image. On the wiki of the project I found this article.
I tried to follow the instructions for it, but in the end I did not manage to add my own package to the source code tree (the build ignored its presence).
Because of this, I tried to find some other way. And it turned out to be a this instruction. I followed the directions from there and compiled my own package.
But as you can see, the source code of that package does not depend on others and does not require any other build header files. Also, his Makefile completely includes instructions for compiling.
define Build/Compile
$(TARGET_CC) $(TARGET_CFLAGS) -o $(PKG_BUILD_DIR)/helloworld.o -c $(PKG_BUILD_DIR)/helloworld.c
$(TARGET_CC) $(TARGET_LDFLAGS) -o $(PKG_BUILD_DIR)/$1 $(PKG_BUILD_DIR)/helloworld.o
endef
But now this does not suit me, since another package that I want to add already has such dependencies.
I tried to bypass them like this (copy the source code to the build folder and call the makefile located there) but nothing came of it:
define Build/Prepare
echo $PKG_NAME
mkdir -p $(PKG_BUILD_DIR)
cp $(SOURCE_DIR)/* $(PKG_BUILD_DIR)
$(Build/Patch)
endef
define Build/Compile
$(PKG_BUILD_DIR) $(MAKE)
endef
I am getting next output:
$ make -C package/feeds/mypackages/helloworld compile TOPDIR=$PWD
make: Entering directory '/home/username/mypackages/examples/helloworld'

And actually my question is, what needs to be set in the Makefile to copy files correctly and call the local Makefile for package binary?
In order to copy files and directories you can use below step:
# copy all files and directories using **cp -r -f **
define Build/Prepare
echo $PKG_NAME
mkdir -p $(PKG_BUILD_DIR)
cp -r -f $(SOURCE_DIR)/* $(PKG_BUILD_DIR)
$(Build/Patch)

In order to execute the local makefile use below step:
# Execute local makefile by giving path using '-C' option
define Build/Compile
`$(MAKE) -C $(PKG_BUILD_DIR)`

I'm trying to replicate the result of this github repo using Google Colab since I don't want to install all the requirements on my local machine and to take advantage of the GPU on Google Colab
However, one of the things I need to do (as indicated in the repo's README) is to first compile a cpp makefile. The instruction of the makefile is included below. Obvious I can't follow this instruction since I don't know Google Colab's directories of ncvv, cudalib and tensorflow library
cd latent_3d_points/external
with your editor modify the first three lines of the makefile to point to
your nvcc, cudalib and tensorflow library.
make
Is there a way for me to compile the files included in the makefile (because those functions are needed to run the model) either using the makefile directly or compile each cpp file individually? I included the content of the makefile below to avoid having you to click around in the repo looking for it
nvcc = /usr/local/cuda-8.0/bin/nvcc
cudalib = /usr/local/cuda-8.0/lib64
tensorflow = /orions4-zfs/projects/optas/Virt_Env/tf_1.3/lib/python2.7/site-packages/tensorflow/include
all: tf_approxmatch_so.so tf_approxmatch_g.cu.o tf_nndistance_so.so tf_nndistance_g.cu.o
tf_approxmatch_so.so: tf_approxmatch_g.cu.o tf_approxmatch.cpp
g++ -std=c++11 tf_approxmatch.cpp tf_approxmatch_g.cu.o -o tf_approxmatch_so.so -shared -fPIC -I $(tensorflow) -lcudart -L $(cudalib) -O2 -D_GLIBCXX_USE_CXX11_ABI=0
tf_approxmatch_g.cu.o: tf_approxmatch_g.cu

You can use the bash like on your pc by adding %%bash in the colab's cells.
Example:
Cell one: write cpp file
%%writefile welcome.cpp
#include <iostream>
int main()
{
std::cout << "Welcome To AI with Ashok's Blog\n";
return 0;
}
Cell two: compile and run
%%bash
g++ welcome.cpp -o welcome
./welcome
You can also open the cpp file in colab's build-in text editor in order to enjoy correct highlights. It opens when you open a text file from the "Files" tab on the left and can be save with "ctr+s" shortcut.
You can install the required version of Cuda in google colab. For eg.
For Cuda 9.2 you can try
!apt-get --purge remove cuda nvidia* libnvidia-*
!dpkg -l | grep cuda- | awk '{print $2}' | xargs -n1 dpkg --purge
!apt-get remove cuda-*
!apt autoremove
!apt-get update
!wget https://developer.nvidia.com/compute/cuda/9.2/Prod/local_installers/cuda-repo-ubuntu1604-9-2-local_9.2.88-1_amd64 -O cuda-repo-ubuntu1604-9-2-local_9.2.88-1_amd64.deb
!dpkg -i cuda-repo-ubuntu1604-9-2-local_9.2.88-1_amd64.deb
!apt-key add /var/cuda-repo-9-2-local/7fa2af80.pub
!apt-get update
!apt-get install cuda-9.2
Similarly, you can find a way to install Cuda 8.2.
For gcc
!apt-get install -qq gcc-5 g++-5 -y
!ln -s /usr/bin/gcc-5
!ln -s /usr/bin/g++-5
!sudo apt-get update
!sudo apt-get upgrade
Then you can compile it or make it by running make, if your installation has a custom make file.
!make
I'm trying to compile a program called ZEUS and I am following the included instructions exactly but I came across the following error.
The instructions asked me to type csh -v namelist.s in the folder containing namelist.s. This is a fairly large assembly file which invokes another file given in the source files called bldlibo which is the csh file mentioned in the title. The contents of this file are:
#==== SCRIPT TO BUILD AN OBJECT LIBRARY FROM A FORTRAN SOURCE FILE====#
#
# Syntax: bldlibo <library name> <source code>
# eg: bldlibo namelist.a namelist.f
#
rm -rf bldlibo.dir
mkdir bldlibo.dir
cp $2 bldlibo.dir
cd bldlibo.dir
fsplit $2 >& /dev/null
rm $2
#
# When -fast option is used, this leads to the __vsincos_ unsatisfied
# external errors when zeus is compiled with -g option. Thus, use -O4
# instead.
#
ifort -c -O4 *.f
#f77 -c -g -C -ftrap=common *.f
ar rv $1 *.o >& /dev/null
ranlib $1
cd ..
mv bldlibo.dir/$1 .
rm -r bldlibo.dir
When I run csh -v namelist.s it begins to run bldlibo and works fine up until ifort is invoked at which point it says ifort: no match. I have tried adding #!/bin/csh at the start and also source .../ifortvars.csh but that didn't work.
Can anybody help me, sorry if I haven't explained it well enough.
