I'm trying to install WWW::HTMLUnit on Windows 7. There're step that I run through:
Install Inline::Java 0.53
Install WWW::HTMLUnit 0.15
At step 2, after nmake, I type nmake test to test module but it failed. Here's output:

From above log, I could see that:

I have no idea that I missed anything.
Any help would be appreciated.

I found it.
There's different between path in Unix and Windows system. Unix uses ':' for a delimiter but Windows uses ';'. So what I've done is that open HTMLUnit.pm and change all of ':' to ';'.
With HTMLUnit version 0.15 I made changes at these lines below:
Line 78:
return join ';', map { "$jar_path/$_" } qw( # return join ':', map { "$jar_path/$_" } qw(
Line 127:
$custom_jars = join(';', #{$parameters{'jars'}}); # $custom_jars = join(':', #{$parameters{'jars'}});
Line 148:
CLASSPATH => collect_default_jars() . ";" . $custom_jars, # CLASSPATH => collect_default_jars() . ":" . $custom_jars,
And it works like a magic.
(it wouldn't let me comment on an existing answer)
I see your answer about ':' vs ';'. I'll try to include a fix in the next WWW::HtmlUnit release (I am the author of the perl bindings).

Recently I posted a question about some basic scala code. I got some useful responses that emphasized that scala2 and and scala3 are very different programming languages. Since I have scala3, I was careful enough to work out only scala3 examples, such as this one:
#main def happyBirthday(age: Int, name: String, others: String*) =
val suffix =
age % 100 match
case 11 | 12 | 13 => "th"
case _ =>
age % 10 match
case 1 => "st"
case 2 => "nd"
case 3 => "rd"
case _ => "th"
val bldr = new StringBuilder(s"Happy $age$suffix birthday, $name")
for other <- others do bldr.append(" and ").append(other)
bldr.toString
I compile it as scalac happyBirthday.scala and run as scala happyBirthday 23 Lisa Peter
Illegal command line: java.lang.NumberFormatException: For input
string: "happyBirthday"`
This reminded me very much the issue observed in a comment to this post. #LuisMiguelMejíaSuárez suggested that a workaround could be to compile to jar. I did exactly that using this recipe
scalac happyBirthday.scala -d happyBirthday.jar
and run
java -jar happyBirthday.jar 23 Lisa Peter
Error: A JNI error has occurred, please check your installation and
try again Exception in thread "main" java.lang.NoClassDefFoundError: scala/util/CommandLineParser$ParseError
I wonder what's wrong with this code? Notice that "#main methods are the recommended scheme to generate programs that can be invoked from the command line in Scala 3." according to this reference.
I am trying to cross-compile openjdk 11u to aarch64. I am using following command:
bash configure --openjdk-target=aarch64-linux-gnu --disable-warnings-as-errors
next I use make command to compile openjdk, but iam getting output errors below:

everyone, I am using tabula-py in python to extract table from pdfs. I used following codes.
import tabula
table_temp = tabula.read_pdf('./example_pdf/sample1.pdf',pages=11)
However, I got the error message as pasted below, in which I was told "no such file or directory: 'java'". I have installed Java in the following folder
"/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home".
Could anyone help me on solving the problem?
Thanks.

I had run into the same error. The line actually causing the error for me was subprocess.call('java').
Installing Java on my machine fixed the error for me.
If installing Java still doesn't solve the problem for you, try running which java, and add the output directory to your PATH environment variable.
I'm building an android rom from the android source code but after about 5 minutes it gives this error.
error: ro.build.fingerprint cannot exceed 91 bytes: Android/mini_emulator_x86/mini-emulator-x86:5.0.555/AOSP/username02280306:userdebug/test-keys (97)
make: *** [out/target/product/mini-emulator-x86/system/build.prop] Error 1
make: *** Deleting file `out/target/product/mini-emulator-x86/system/build.prop'
make: *** Waiting for unfinished jobs....
How do I increase the ro.build.fingerprint size limit?
Plus I'm building on a Mac.
Edit build/tools/post_process_props.py. Change lines as follows:
PROP_NAME_MAX = 31
# PROP_VALUE_MAX = 91
PROP_VALUE_MAX = 128
Edit bionic/libc/include/sys/system_properties.h. Change lines as follows:
#define PROP_NAME_MAX 32
// #define PROP_VALUE_MAX 92
#define PROP_VALUE_MAX 128
Do
make clean
make
You can also run the second make command in parallel using syntax such as
make -j8
Alternatively, you can specify the build fingerprint string as command line argument to make using:
make -j5 BUILD_FINGERPRINT="....."
This will allow you to stay within the 91 byte limit.
I have a Java application installed on a USB which the user should be able to run from any OS.
For this,
I'm packaging a JRE instance on the USB along with my application.
I'm having a FAT32 file-system on the USB.
However, the problem is, FAT32 has no concept of execute ("+x") permissions. While I can launch a shell script, like so:
$ sh /path/to/fat32-usb/helloWorld.sh
, and while I can launch a simple ELF binary, like so:
$ /lib64/ld-linux-x86-64.so.2 /path/to/fat32-usb/helloWorld
, I can't seem to be able to launch the Java ELF program. I get these errors:
Error: could not find libjava.so
Error: Could not find Java SE Runtime Environment.
Before launching java, I've tried setting these environment variables as follows:
export JAVA_HOME=/path/to/fat32-usb/jre
export LD_LIBRARY_PATH="$JAVA_HOME/lib/amd64:.:$LD_LIBRARY_PATH"
export PATH="$JAVA_HOME/bin:.:$PATH"
I have also tried launching java from inside the $JAVA_HOME/bin directory. Finally, I've also tried copying all the libXXX.so's from $JAVA_HOME/lib/amd64/ to $JAVA_HOME/bin, hoping that they would get picked up from the current directory, ., somehow.
But nothing has worked.
EDIT
Here are the last few lines of strace output:
$ strace -vfo /tmp/java.strace /lib64/ld-linux-x86-64.so.2 /path/to/fat32-usb/jre ...

This is ltrace excerpt around loading of libjava.so by a Java on an ext4 partition (and not the problem FAT32 partition), which I can load fine:
