Why this warning from IBM XL C/C++ compiler?

阅读更多关于 Why this warning from IBM XL C/C++ compiler?

问题 Here's a minimum code example that illustrates the problem: #include <iostream> class Thing { // Non-copyable Thing(const Thing&); Thing& operator=(const Thing&); int n_; public: Thing(int n) : n_(n) {} int getValue() const { return n_;} }; void show(const Thing& t) { std::cout << t.getValue() << std::endl; } int main() { show(3); } This yields the same error: int main() { show( Thing(3) ); } IBM XL C/C++ 8.0 compiler under AIX emits these warnings: "testWarning.cpp", line 24.9: 1540-0306 (W)

How to overcome an incompatibility between the ksh on Linux vs. that installed on AIX/Solaris/HPUX?

阅读更多关于 How to overcome an incompatibility between the ksh on Linux vs. that installed on AIX/Solaris/HPUX?

I am involved in the process of porting a system containing several hundreds of ksh scripts from AIX, Solaris and HPUX to Linux. I have come across the following difference in the way ksh behaves on the two systems: #!/bin/ksh flag=false echo "a\nb" | while read x do flag=true done echo "flag = ${flag}" exit 0 On AIX, Solaris and HPUX the output is "flag = true" on Linux the output is "flag = false". My questions are: Is there an environment variable that I can set to get Linux's ksh to behave like the other Os's'? Failing that: Is there an option on Linux's ksh to get the required behavior?

How to return memory from process to the OS

阅读更多关于 How to return memory from process to the OS

I have an issue with memory management in various operating systems. My program is a server that does some processing that could take a few GB of memory. After that, it releases most of the memory while it waits for a few hours until another request arrives. On AIX and Solaris, I observe the following behavior, When I free memory, the memory is not returned back to the operating system. The amount of virtual memory used by a process always increases - never decreases. The same is true for the physical memory, up to its limit. Thus it appears that we use all this memory in sleep mode as well.

When formatting a number to be printed, 12 digit numbers are being formatted with a colon immediately after the dot. Why is this happening?

ksh88 changing single quotes to double quotes inside heredocs?

阅读更多关于 ksh88 changing single quotes to double quotes inside heredocs?

I seem to be running into an issue that's specific to ksh88 that's changing single quotes to double quotes, but only under certain situations involving heredocs and command substitution. Here's an example: #!/bin/ksh # This example works correctly echo "Example 1:" cat <<EOF The 'quick' brown fox "jumped" over the lazy dog. EOF echo # This example is broken echo "Example 2:" var=$(cat <<EOF The 'quick' brown fox "jumped" over the lazy dog. EOF) echo "${var}" echo # This example works correctly echo "Example 3:" var=`cat <<EOF The 'quick' brown fox "jumped" over the lazy dog. EOF` echo "${var}"
