When debugging C + + program, an error is reported. Launch: Program “path” does not exist
solution:
Step 1: delete the launch.json file in the folder. Vscode
Step 2: press F5 to debug the source cpp file, select the first, and then select G + +. Exe
Step 3: debugging succeeded
It’s normal to jump and pass parameters using JSON, but today I don’t know why I reported an error, unexpected end of JSON input,
reason
I found the answer on the Internet because there are unrecognized contents in the passed parameters, and the parameters I passed contain rich text, Therefore, there is no resolution
solution
start with JSON character parameters (parent page) on the page to jump to
issueanswer(item){
let arrar = JSON.stringify(item)
uni.navigateTo({
url:"issueanswer?arr="+encodeURIComponent(arrar)
})
},
Then accept and parse the parameters in onload of the sub page
onLoad(option) {
this.arr =JSON.parse(decodeURIComponent(option.arr))
},
Problems computing Cholesky in quantum espresso reports an error
When running a small system, such as graphene of 11 or elemental iron of 11 * 1, QE calculation reports an error:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
stopping ...
After testing, it is found that this error is due to the use of too many kernel computing and small tasks. For example, if you use 32 small tasks such as accounting, such errors will appear
the solution is to use fewer cores for calculation. For example, on Cheng Chao’s machine, the corresponding statement is modified as follows:
#sbatch -- ntasks per node = 32
to
#sbatch -- ntasks per node = 8
Question:
When using git submodule update, an error is reported:
fatal: Needed a single revision
Unable to find current revision in submodule path 'test'reason:
Git is incorrectly configured, or the code was downloaded from the sub module directory, but the association failed.
Solution:
rm -rf test/Then go back to the root directory of the main module and use the command again:
git submodule update --initBus error (core dumped) occurs in my program, and the error is locked in the fopen part of the code
void dipget(int icdp, int nti, float *dip, char * tanpath)
{
FILE * dfile;
char *filename;
printf("Choose %d from %s\n",icdp, tanpath);
sprintf(filename, "%s%d.x.dat",tanpath, icdp);
printf("Open file: %s \n", filename);
if((dfile = fopen(filename,"rb"))==NULL) // Bus error
{
printf("\n Open %s File error\n",filename);
exit(EXIT_FAILURE);
}
fread(dip, sizeof(float), nti, dfile);
fclose(dfile);
}
Here, you only need to make one step of modification to solve the problem. The reason is very simple. Before using sprintf, you need to allocate a buffer space to it
char *filename;
Change to
char filename[200];
App Store Connect Operation Error ERROR ITMS-90087: “Unsupported architectures.
1. Reason description
the app uses dingxiangcaptchasdk.framework. An error is reported when submitting the app store
reason: dingxiangcaptchasdk.framework contains x86_ 64. I386 architecture. Of course, this app store is not allowed. All errors will be reported when uploading. The solution is to eliminate x86 from this SDK_64, i386 these two architectures
2. Solution
solution: targets – > Build Phases-> Click the plus sign to select new run script phase
to facilitate identification, double-click and rename to supported architectures [x86_64, i386].
Then copy and paste the following code:
APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do

…/Core/Src/main.c(113): error: #29: expected an expression
preface
When defining a macro, you habitually align and type spaces, resulting in an error when calling
1. Wrong situation
#define SDA_High() do{HAL_GPIO_WritePin(I2C_Port,I2C_SDA_Pin,GPIO_PIN_SET);}while(0)
#define SDA_Low () do{HAL_GPIO_WritePin(I2C_Port,I2C_SDA_Pin,GPIO_PIN_RESET);}while(0)
// SDA_Low () Spaces added for alignment
When calling the program
SDA_Low();
SDA_High();
Program error:
…/core/SRC/main. C (113): error: #29: expected an expression
…/core/SRC/main. C (113): error: #65: expected a “;”
solution: remove the space
Summary
Format #define identifier replacement list of macro definition
macro definition uses “identifier” to represent the content in the “replacement list”. The identifier is called the macro name. During preprocessing, the preprocessor will replace all macro names in the source program with the contents in the replacement list in the macro definition. When defining many parameters, it is recommended to use do {} while (0). For reasons, refer to the benefits of using do {} while (0) in macro definition

preface:
This error occurs when using the upload function of egg.
1. Error message:
Error in file name2. Error reporting reason:
There is no configuration file information in config.default.js, but it is directly obtained in the controller, and an error CTX. Request. Files = = undefined is reported
const file = ctx.request.files[0]; //Get uploaded files3. Solution:
Add in config.default.js:
//Enable file mode
config.multipart = {
mode: 'file'
}4. Cause new problems: Invalid filename: order information.xlsx
5. Solutions to new problems and types have to be set. There is a parameter in the upload that is a white list
Add: whitelist: [‘. Xlsx’] in config.default.js
//Enable file mode
config.multipart = {
mode: 'file',
fileSize: 1048576000,
whitelist: ['.xlsx']
}That’s it!
SLOVER installation manual:
① file -> More-> Options
②Add-in
③ Bottom go
④ Check solver add in and confirm to save
⑤ solver will appear in the upper right corner of the data toolbar
Error phenomenon:
the computer with 64 bit Office installed will prompt that the macro is not available after installation
even options -> Trust Center -> Credit center settings -> Macro settings -> Enable all macros and still prompt the same error.
Solution:
① the solver cannot be installed on a 64 bit computer. You can uninstall the local 64 bit office and reinstall 32-bit office.
Or
② Install VMware, build a win10, install an office 32-bit system on the virtual machine, and open network sharing and shared folders
(1) VMware installation reference: the latest super detailed VMware virtual machine download and installation
VMware official website: VMware download
(basically the default installation)
(2) Install virtual machine win10
VMware virtual machine install windows system
(3) Setting shared folders for virtual machines
VMware sets shared folders for windows virtual machines
(4) Virtual machine settings network
I found many strategies and didn’t understand
it turns out that it’s actually very simple
when the virtual machine is turned off, select Edit virtual machine settings
then select network adapter, check bridge mode and copy physical network connection status
OK, turn on the virtual machine again and find that the virtual machine can access the Internet normally
(5) the last step is the installation of 32-bit office
Microsoft Office
come to an official website link, download and install, and finish it.
